President Donald Trump has waived sweeping sanctions and tariffs targeting Russia’s energy revenues, invoking national interest provisions in legislation passed only last month. The decision follows his controversial diesel agreement with Vladimir Putin and threatens to deepen divisions with Congress and European allies over economic pressure on Moscow.

President Donald Trump has suspended the implementation of sweeping American sanctions against Russia, using presidential waiver powers to prevent penalties approved by Congress from taking effect just weeks after he signed them into law.

The executive order issued by the White House on Friday, 16 October, suspends tariffs of up to 500 per cent on Russian imports, alongside penalties targeting major purchasers of Russian oil and gas. It also waives numerous financial and commercial restrictions intended to reduce Moscow’s ability to finance its war against Ukraine.

The decision comes two days before the 18 October deadline for implementing key provisions of the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, which Trump signed on 18 September. The legislation was named after the late Republican senator Lindsey Graham, who had championed tougher economic measures against Russia.

Sanctions established but immediately suspended

The presidential order formally establishes the tariff increases required by the legislation while simultaneously suspending their application.

Under the law, Russian imports into the United States would face additional duties of 500 per cent. A separate provision would impose 100 per cent tariffs on goods imported from the five largest purchasers of Russian crude oil and natural gas if those countries knowingly made new purchases from 18 October, subject to specified conditions and exemptions.

Another provision targets countries identified as leading facilitators of Russian oil sanctions evasion, potentially exposing their exports to similar American penalties.

Trump invoked Section 115 of the legislation, which permits the president to waive sanctions and tariffs after certifying to Congress that doing so serves the national interests of the United States.

The order confirms that the certification and an accompanying explanatory report have been submitted to Congress. However, the publicly released document provides no detailed justification for suspending the measures.

The waivers will remain in effect until the president or designated senior officials decide that further action is appropriate. Existing sanctions imposed under earlier executive orders are explicitly preserved, meaning the decision does not remove all American restrictions against Russia.

Nevertheless, the order prevents the new legislation’s principal economic penalties from operating at a time when Congress had sought to intensify pressure on Moscow.

Diesel agreement shapes Washington’s decision

The suspension follows Trump’s agreement with Putin to facilitate renewed Russian diesel exports, announced on 9 October as part of an effort to reduce international fuel prices.

As EU Today previously reported, the agreement envisages an immediate release of more than 300,000 tonnes of Russian diesel, followed by additional shipments in November and subsequent months. Washington also authorised certain transactions involving Russian diesel until April 2027.

The arrangement has raised questions about the relationship between the administration’s energy policy and sanctions intended to constrain Russia’s war economy.

Diesel prices have become an increasingly important domestic political issue ahead of the American congressional elections on 3 November. The war involving Iran and disruptions to international energy supplies have contributed to exceptionally high fuel costs, creating additional pressure on the administration.

The White House hopes additional Russian supplies will relieve pressure on international markets. However, energy analysts have questioned whether the quantities involved will materially affect American prices, particularly before the elections.

The latest waiver also removes the immediate threat of punitive tariffs against major Russian energy customers, including China and India, which had objected to the proposed measures.

Congressional opposition and European concerns

The decision is likely to intensify opposition within Congress, where the sanctions legislation attracted substantial bipartisan support.

Earlier this week, 12 senators, including six Republicans, called on Trump to reverse his diesel agreement, arguing that allowing Russian fuel back onto international markets would provide Moscow with additional revenue for its military operations.

Democratic Senator Richard Blumenthal, who helped develop the sanctions legislation, criticised the diesel arrangement as contrary to Congress’s intention to strengthen economic pressure on Russia.

The decision also exposes a widening divergence between Washington and Brussels.

At the European Council meeting on Friday, European Commission President Ursula von der Leyen and European Council President António Costa reaffirmed that EU sanctions against Russia would remain in place until Moscow ended its war against Ukraine.

Costa declared that the present circumstances required increased pressure on Moscow rather than a relaxation of existing restrictions. The European Union is also preparing a 22nd sanctions package while considering additional financial support for Kyiv.

For Ukraine, the decision means that Russia will continue to benefit from energy exports and the international trade that helps finance its war. Instead of tightening restrictions on these revenues, Washington has suspended measures specifically intended to cut them.

The timing is particularly significant. While Trump is pressing Kyiv to halt attacks on Russian oil refineries and other energy facilities, Moscow continues its strikes against Ukrainian cities and civilian infrastructure. Zelenskyy has argued that Ukraine cannot be expected to stop targeting Russia’s energy sector while Russian attacks on Ukrainian infrastructure continue.

Although Trump can reinstate the sanctions, his decision removes the immediate threat of additional penalties against Russia and its principal energy customers. It also places Washington increasingly at odds with its European allies. Brussels remains committed to maintaining and expanding sanctions against Moscow, while the White House is now giving priority to reducing American fuel prices, even if that means easing economic pressure on Russia.

Ukraine was prepared to suspend attacks on Russian oil refineries if Washington supplied anti-ballistic missile systems to protect its energy infrastructure, President Volodymyr Zelenskyy has revealed. The proposed compromise was not accepted, despite American pressure on Kyiv to halt its strikes.

Ukrainian President Volodymyr Zelenskyy has disclosed that Kyiv offered to suspend attacks on Russian oil refineries in exchange for temporary American anti-ballistic missile protection for Ukraine’s energy infrastructure. Washington did not provide the requested systems, leaving Ukraine exposed to continued Russian missile strikes while the United States sought to restrict Ukrainian operations against Russia’s oil industry.

Speaking at a press conference in Brussels on Friday, 16 October, Zelenskyy said the proposal had been presented to Washington as a compromise following President Donald Trump’s agreement with Vladimir Putin on Russian diesel supplies and restrictions on attacks against energy facilities.

The Ukrainian president confirmed that Kyiv had not been consulted before Washington reached its understanding with Moscow. He described the diesel agreement as a surprise and objected to arrangements determining Ukraine’s military actions without its participation. Any agreement concerning Ukrainian strikes on Russian territory, he argued, required consultation with the Ukrainian government.

Nevertheless, Zelenskyy said Ukraine had been willing to accommodate American demands, even under an arrangement that did not require Russia to suspend its own attacks. Instead of insisting on reciprocal restrictions, Kyiv proposed receiving sufficient anti-ballistic missile systems to protect its electricity network for the duration of the requested suspension.

The proposal reflected Ukraine’s immediate security requirements. Russia has repeatedly targeted power stations, substations and other critical infrastructure, while Ukrainian forces have attacked Russian refineries to disrupt fuel production and reduce revenues available to Moscow. Halting the Ukrainian campaign without additional defensive capabilities would have left Kyiv surrendering one means of economic pressure while remaining vulnerable to Russian bombardment.

Zelenskyy said he had asked Washington for a limited number of systems, rather than a substantial new military commitment. The proposed deployment would have lasted only as long as the United States required Ukraine to refrain from attacking Russian refineries. However, according to the president, no such assistance was provided.

US diesel agreement deepens dispute

The disagreement follows the diesel arrangement announced by Trump on 9 October, under which Russia agreed to resume substantial petroleum product exports to American and international markets. Washington also authorised certain transactions involving Russian diesel, easing restrictions previously intended to reduce Moscow’s energy revenues.

The agreement created a direct conflict between American energy policy and Ukraine’s strategy of targeting Russian refining capacity. Washington wants additional diesel supplies to ease pressure on fuel markets, while Kyiv regards attacks on oil infrastructure as a means of weakening Russia’s ability to sustain its invasion.

That disagreement intensified after Ukraine resumed attacks on Russian refineries, including a strike against a facility in the Ryazan region. Trump criticised the operations, accusing Kyiv of contributing to higher global oil prices. Zelenskyy, meanwhile, argued that increased Russian diesel revenues would provide Moscow with additional resources to finance its military campaign.

The Ukrainian president’s proposal also exposed the limitations of the temporary energy ceasefire promoted by Washington. Russia continued attacks against Ukrainian civilian infrastructure, including electricity facilities, despite the American initiative. Kyiv’s proposed compromise would have addressed the resulting imbalance by providing defensive protection rather than relying on Russian restraint.

Russian strikes underline Ukraine’s defensive requirements

The urgency of Ukraine’s request was illustrated by renewed Russian attacks during Zelenskyy’s visit to Brussels. According to the Ukrainian presidency, strikes on 15 October damaged energy infrastructure in several regions, leaving almost 15,000 people without electricity in Volyn and disrupting supplies in parts of Kyiv and the surrounding region.

Ukraine continues to face shortages of the interceptors required to defend against ballistic missiles. Zelenskyy has identified anti-ballistic capabilities as an immediate priority, particularly as Russia intensifies attacks ahead of winter. During talks with NATO Secretary General Mark Rutte, he stressed the need for additional missile interceptors and other air defence equipment.

The president also raised these requirements during Friday’s meeting with European Commission President Ursula von der Leyen and European Council President António Costa. Discussions covered air defence, protection of energy infrastructure and financial assistance needed to sustain Ukraine’s resistance to Russian aggression.

European leaders support Kyiv’s position

Zelenskyy said European leaders had supported Ukraine’s position in the dispute with Washington. His remarks came as the EU reaffirmed its intention to maintain economic pressure on Moscow despite the Trump administration’s decision to facilitate Russian diesel exports.

As EU Today reported earlier on Friday, von der Leyen and Costa rejected any relaxation of European sanctions while Russia continues its war. The Commission is preparing a further sanctions package, maintaining a policy intended to restrict Moscow’s ability to finance its military operations.

The contrasting American and European positions have become increasingly significant for Kyiv. Washington is seeking to stabilise fuel markets through arrangements with Moscow, while European governments remain committed to reducing Russian energy revenues and strengthening Ukraine’s military and economic resilience.

For Zelenskyy, the unresolved question is whether Ukraine can be expected to limit attacks on Russian oil infrastructure while receiving neither reciprocal guarantees from Moscow nor additional protection against Russian ballistic missiles. His account of the unsuccessful American negotiations indicates that Kyiv was prepared to compromise, but only if its immediate defensive needs were addressed.

Ukraine's president, Volodymyr Zelenskyy, was asked by Sky News at a press conference in Brussels, Belgium, if he felt he was being made a 'scapegoat' by his US counterpart, Donald Trump, for domestic problems including high diesel prices before midterm elections. Zelenskyy paused for 15 seconds, before he eventually smiled and said: 'This is my answer.'

Drone strikes against merchant vessels off Bulgaria have brought Russia’s war into waters bordering NATO and the European Union. With grain exports threatened, shipping costs rising and Sofia seeking allied protection, Moscow’s campaign against maritime trade risks becoming another instrument of economic and political pressure.

Russia’s expanding campaign against commercial shipping in the Black Sea is creating a security crisis that extends far beyond Ukraine. The latest drone attacks off Bulgaria’s coast have left 11 sailors missing, forced Sofia to seek assistance from NATO and the European Union, and raised concerns that Moscow is attempting to disrupt one of the world’s principal agricultural export routes.

On 13th October, the Guinea-Bissau-flagged HS Dignity sank after being struck by drones approximately 17 nautical miles east of the Bulgarian village of Krapets. Another vessel, the Ukrainian-owned, Maltese-flagged Chelsea 3, was attacked near Byala. All 15 crew members were rescued, although five sustained minor injuries. The incidents followed earlier attacks in Bulgaria’s exclusive economic zone on 6th October, when the ALFA WATAN sank and the grain-carrying ABLE was damaged.

The significance lies not simply in the destruction of merchant vessels but in the geographical expansion of the threat. Commercial routes previously regarded as comparatively safer alternatives to Ukraine’s exposed ports are now becoming operationally dangerous. Bulgaria and Romania, both NATO and EU members, face disruption to trade, maritime insurance and port operations as the conflict spreads across the western Black Sea.

Russia’s Campaign Against Maritime Trade

The latest attacks follow months of Russian strikes against Ukrainian ports, export terminals and civilian shipping. As EU Today previously reported, repeated attacks on Odesa have already reduced Ukraine’s grain-export capacity, while alternative routes through the Danube and neighbouring European countries cannot fully replace its major Black Sea terminals.

The extension of attacks towards Bulgaria changes the economic calculation. Ships carrying agricultural products, those approaching Danube ports and vessels operating between Black Sea countries now face greater uncertainty, regardless of whether they enter Ukrainian territorial waters.

Maritime security company Ambrey assessed the earlier October attacks as highly likely to have been conducted by Russian forces. Its assessment identified vessels associated with Ukrainian grain trade as the principal targets, rather than suggesting that every commercial ship was being attacked indiscriminately.

This distinction is important, but it offers little reassurance to international shipping companies. A campaign directed against Ukrainian trade can disrupt the wider maritime economy when insurers, shipowners and exporters cannot establish which routes remain safe.

The economic consequences are already becoming apparent. Shipowners must consider higher insurance premiums, additional security measures and the possibility of losing vessels and crews. Traders may redirect cargoes or withdraw from routes whose commercial returns no longer justify the risks.

Radev Confronts the Consequences of Moscow’s War

The attacks have also placed Bulgarian Prime Minister Rumen Radev in an increasingly difficult political position.

Radev has advocated renewed diplomatic engagement with Moscow and questioned the emphasis placed on military assistance to Ukraine. He has rejected accusations of being pro-Russian, presenting his approach as a pragmatic alternative to prolonged confrontation.

Yet the attacks have demonstrated the limitations of maintaining political distance from a war whose economic and security consequences are reaching Bulgarian waters.

After summoning Russian Ambassador Eleonora Mitrofanova on 13th October, Radev acknowledged that Bulgaria possessed no conclusive evidence establishing responsibility for the latest strikes. Nevertheless, he argued that their consequences benefited Russia and questioned why Ukraine would attack its own commercial vessels.

According to the Bulgarian News Agency’s account of the meeting, the prime minister also warned that higher insurance costs and shipping companies’ reluctance to serve Bulgarian ports were already damaging the national economy.

This is the fundamental change confronting Sofia. The conflict is no longer solely a question of Bulgaria’s position towards Ukraine or its diplomatic relationship with Russia. It is affecting the country’s commercial interests, energy supplies and responsibilities as a NATO member.

Radev’s response does not necessarily indicate a wholesale reversal of his previous political position. It demonstrates that the practical obligations of government can leave considerably less room for accommodation with Moscow than the arguments advanced from outside direct responsibility for national security.

Food Security Becomes Another Instrument of Pressure

The broader consequences may be felt most severely outside Europe.

Ukraine remains an important supplier of wheat, maize and vegetable oils to international markets, including countries in Africa, Asia and the Middle East. Interruptions to these exports affect more than Ukraine’s agricultural revenues. They can increase transport costs, delay deliveries and reduce the availability of competitively priced food in import-dependent countries.

Speaking at the Warsaw Security Forum on 12th October, President Volodymyr Zelenskyy warned of a possible agricultural crisis, arguing that Russian interference with Black Sea shipping could leave countries in Africa, Asia and the Middle East facing serious supply difficulties within months.

The warning reflects a mechanism already familiar from the earlier stages of Russia’s invasion. Following Moscow’s withdrawal from the UN-brokered grain agreement in July 2023, Ukrainian agricultural exporters faced renewed attacks on port infrastructure and substantial uncertainty over maritime access.

The danger is not necessarily an immediate worldwide shortage of grain. Wheat prices remained relatively steady following the 13th October incidents. Rather, sustained disruption could progressively reduce available export capacity, increase costs and place vulnerable importing countries under greater pressure.

For Moscow, such disruption could serve several purposes simultaneously: weakening Ukraine’s economy, raising the costs of international support for Kyiv and creating additional pressures on governments concerned about food inflation and social stability.

Europe’s Black Sea Security Strategy Faces a Practical Test

The immediate challenge for Brussels and NATO is how to protect commercial navigation without allowing the conflict to expand into a direct military confrontation.

Bulgaria has requested stronger air and maritime surveillance and is seeking closer coordination with Romania and Turkey. Defence Minister Dimitar Stoyanov said on 14th October that Sofia expected to join a NATO counter-drone initiative by the end of the month.

The EU has already developed a framework for addressing precisely such threats. Its Black Sea strategy, announced in May 2025, proposed a maritime security hub integrating surveillance, intelligence-sharing, infrastructure protection and regional cooperation.

The attacks now expose the difference between developing a security framework and providing effective protection to merchant vessels. Better intelligence can identify threats, but preventing further sinkings requires detection systems, coordinated responses and sufficient defensive capabilities.

Turkey’s involvement is particularly important because of its control over the Bosphorus and Dardanelles and its established role in Black Sea maritime security. Any workable regional arrangement must therefore extend beyond cooperation between Bulgaria and Romania.

The incidents occurred outside Bulgaria’s 12-nautical-mile territorial sea, meaning they do not automatically constitute an armed attack on NATO territory under Article 5. Nevertheless, repeated strikes within the economic zones of alliance members pose a substantial challenge to maritime security.

Russia’s campaign against Ukrainian exports is increasingly imposing costs on neighbouring European states and international trading partners. The question facing the EU is whether it can secure the commercial routes on which both Ukraine’s economy and the food supplies of millions beyond Europe depend.

Volodymyr Zelenskyy’s unusually direct criticism of Donald Trump marks a turning point in relations between Kyiv and Washington. With American satellite restrictions disrupting Ukrainian military operations, intelligence cooperation under scrutiny and the White House easing pressure on Russian energy exports, Ukraine faces a fundamental question: how can it defend itself when its most powerful partner is increasingly willing to accommodate Moscow?

President Volodymyr Zelenskyy has abandoned much of the diplomatic restraint that characterised his dealings with Donald Trump since their confrontation in the Oval Office in February 2025. In an interview on 14 October, the Ukrainian president accused his American counterpart of moving towards Russia and choosing the wrong side of history.

His intervention followed a series of American decisions that have increased pressure on Kyiv while offering Moscow economic and diplomatic advantages. A controversial agreement involving Russian diesel exports, uncertainty surrounding the provision of American intelligence and sudden restrictions on military satellite communications have brought relations between the two countries to their most difficult point since Trump’s return to the White House.

Zelenskyy’s criticism was unusually personal. Questioned about whether he felt betrayed by Washington’s recent decisions, he acknowledged the sense of betrayal but emphasised that Ukraine’s survival could not be treated as a commercial negotiation. He said Ukraine was not selling its country and argued that an American president claiming to act as an intermediary must not favour one of the belligerents.

The shift reflects the apparent exhaustion of a strategy Kyiv has pursued for more than a year: avoid openly challenging Trump, maintain personal contact with the White House and hope that American support can be preserved through diplomatic accommodation. That calculation is becoming increasingly difficult to sustain as Washington’s demands threaten to constrain Ukraine’s military operations without producing corresponding concessions from Russia.

American leverage becomes a Ukrainian vulnerability

The immediate demonstration of Ukraine’s dependence on American technology came during the night of 13–14 October, when SpaceX imposed restrictions on Starshield, the military-grade version of its Starlink satellite communications service.

According to accounts provided by Ukrainian frontline commanders, the changes disrupted connections to terminals travelling above approximately 160 kilometres per hour, forcing the abandonment of several drone missions. The restrictions affected systems used for reconnaissance, interception and strikes against Russian military targets.

As EU Today reported on 14 October, the disruption exposed a weakness extending beyond individual drone missions. Satellite communications form part of Ukraine’s operational infrastructure, supporting the movement of battlefield information, remote weapons control and communications across areas where conventional networks are vulnerable to Russian electronic warfare.

An interruption imposed remotely by a commercial provider can therefore affect military capabilities without any physical attack on Ukrainian equipment. Decisions taken outside Ukraine’s military command structure can alter the effectiveness of systems already deployed on the battlefield.

Ukraine’s Defence Ministry subsequently opened discussions with American officials, SpaceX and NATO partners while examining alternative communications arrangements.

Later on Wednesday, former Ukrainian defence minister Mykhailo Fedorov announced that Starlink functionality at speeds up to 160 kilometres per hour was being restored. Work was still required to remove the restrictions on Starshield altogether. The partial reversal offered immediate operational relief but did not resolve the underlying dependency.

There is no established evidence that the Trump administration ordered SpaceX to impose the restrictions. Nevertheless, their timing, amid mounting disagreements over Ukraine’s military operations, has reinforced Kyiv’s concerns about relying on communications infrastructure controlled by an American company.

Intelligence warnings and the protection of civilians

The dispute over satellite access coincides with growing uncertainty about American intelligence cooperation.

Following Russian ballistic missile strikes on Kyiv on 12–13 October, Zelenskyy complained that Ukraine had received no advance warning from its international partners. The attacks damaged residential buildings and energy infrastructure, while Ukraine’s authorities raised concerns about the absence of advance intelligence.

Advance information about Russian missile launches is particularly important when ballistic weapons leave civilians only minutes to reach shelters. Intelligence cooperation also supports Ukrainian air-defence units in assessing threats and preparing interceptions.

Trump denied on 13 October that Washington had stopped sharing intelligence with Ukraine. Ukrainian Foreign Minister Andrii Sybiha likewise confirmed that cooperation continued. The absence of warnings about particular attacks therefore cannot be equated with a complete suspension of American assistance.

Yet the consequences of unreliable warning arrangements remain serious. For Ukraine, the distinction between information withheld, delayed or simply unavailable offers little protection when Russian ballistic missiles reach civilian neighbourhoods without sufficient warning.

The wider concern is that intelligence provision could become another instrument of diplomatic pressure. Accounts of negotiations over Ukrainian attacks on Russian refineries have raised the possibility that Washington might use such assistance as leverage. Reports of explicit threats have been disputed, but the controversy has increased uncertainty surrounding a capability central to Ukraine’s defence.

Why the diesel agreement changes the strategic calculation

The confrontation has also exposed a contradiction in Washington’s approach to the war.

Trump’s agreement allowing Russian diesel to return to international markets offers Moscow additional export opportunities at a time when Ukrainian attacks have damaged refining capacity and disrupted domestic fuel supplies.

The American administration has justified the arrangement partly through the need to ease fuel prices. Yet the initially announced quantities are modest in relation to international petroleum markets, raising questions about how much immediate relief the measure can realistically provide.

For Putin, its diplomatic significance may be considerably greater. Russia has secured a relaxation of American economic restrictions while Washington simultaneously presses Kyiv to limit attacks on the infrastructure that generates revenue for Moscow’s war economy.

The commercial implications of Washington’s sanctions reversal extend beyond the initial shipment volumes. The Treasury authorisation permits certain transactions involving Russian-origin diesel until April 2027, creating opportunities for international traders and financial intermediaries while leaving the broader sanctions framework formally intact.

Trump’s proposed energy ceasefire has compounded the difficulty. As EU Today examined earlier this week, Kyiv has offered to suspend strikes against Russian energy facilities if Moscow reciprocates. Russian attacks on Ukrainian power infrastructure have nevertheless continued.

An arrangement in which Ukraine stops targeting Russian refineries while Russia retains the ability to strike Ukrainian electricity generation would remove an important source of pressure on Moscow without protecting Ukrainian civilians.

Such an outcome would change the military and economic conditions of the war in Russia’s favour, regardless of how Washington describes its diplomatic objectives.

The White House, Congress and the limits of presidential power

Zelenskyy’s sharper language also reflects a possible reassessment of where influence over American policy can be exercised.

For much of Trump’s second presidency, Kyiv’s diplomacy has concentrated on preserving a workable relationship with the president himself. That approach assumes that personal engagement can influence White House decisions even when Trump’s broader political instincts favour accommodation with Putin.

The events of October suggest that this strategy has reached its limits.

Ukraine’s alternative is not necessarily an outright confrontation with Washington. Rather, it involves placing greater weight on Congress, the American defence establishment and the institutional relationships that have supported Ukraine since Russia’s full-scale invasion in February 2022.

There is a historical precedent. During Trump’s first presidency, Congress supported military assistance to Ukraine despite differences within the administration over relations with Russia. Under Joe Biden, congressional resistance also demonstrated how domestic American politics could determine the timing and scale of weapons deliveries.

The months-long delay in approving the 2024 military assistance package contributed to severe ammunition shortages at a critical stage of Russia’s offensive operations. Ukraine’s loss of Avdiivka illustrated the danger of making battlefield planning dependent on political negotiations in Washington.

The congressional elections on 3 November 2026 could alter the balance of power. A change in control of either chamber would increase opportunities for oversight, investigations and legislative pressure on the administration, although Congress cannot independently direct every aspect of intelligence sharing or presidential diplomacy.

A less compliant Congress could nevertheless make it politically harder for the White House to restrict Ukrainian assistance without explanation.

Europe confronts a more permanent problem

For European governments, the dispute carries implications extending well beyond the immediate confrontation between Trump and Zelenskyy.

The transatlantic security relationship has historically depended on the assumption that American military capabilities, intelligence networks and political commitments would remain available to European allies during a major security crisis.

That assumption is increasingly difficult to reconcile with an American administration prepared to link assistance to Ukraine with wider commercial negotiations and domestic political objectives.

The consequences are particularly acute in areas where European capabilities remain insufficient to replace American systems quickly, including satellite intelligence, strategic reconnaissance, missile defence and specialised communications.

Europe can expand weapons production, finance Ukrainian purchases and develop alternatives to American technology. Replacing the full range of capabilities provided by the United States, however, requires investment measured in years rather than months.

The problem will not necessarily disappear when Trump leaves office. His return to power demonstrated that the American foreign-policy consensus which supported European security for decades can be challenged through the electoral process.

Future American administrations may seek to restore traditional alliances, but European governments must now account for the possibility that another election could reverse those commitments.

For Zelenskyy, the immediate calculation is exceptionally difficult. Public criticism risks provoking further retaliation from a president whose administration still controls capabilities essential to Ukraine’s defence. Continued diplomatic restraint, however, has not prevented Washington from offering concessions to Russia or introducing uncertainty into Ukraine’s military planning.

His latest intervention suggests that Kyiv is no longer convinced that avoiding confrontation will preserve American support. The question is whether greater political scrutiny of Washington’s decisions can prevent a further erosion of assistance before Russia turns the resulting military advantages into territorial gains.

The air war between Russia and Ukraine has intensified as the conflict stretches into its fifth year following Moscow’s invasion of its neighbour.
