Ukraine tensions have deepened after a difficult period in relations between US President Donald Trump and Ukrainian President Volodymyr Zelensky. Although talks in Oslo ended with signs of cautious progress, disagreements over military support, intelligence sharing and US dealings with Russia continue to raise concerns in Kyiv and across Europe.
The meeting between Trump envoy Steve Witkoff and Zelensky began with a public show of goodwill, including an embrace shared in a video posted by the Ukrainian president. Zelensky said Ukraine remained committed to peace and thanked its partners for their support. However, the positive imagery came after days of increasingly hostile rhetoric from Washington.
Ukraine tensions grow as Trump criticises Zelensky
Trump has questioned Zelensky’s judgment and described him as a difficult partner for the United States. He has also blamed the Ukrainian leader for obstructing efforts to negotiate an end to the war. Zelensky, while usually careful in his public comments about Washington, has responded with growing frustration.
Addressing US lawmakers, Zelensky referred to American decisions that were difficult to understand “between friends” and warned that political choices could be slowing assistance to Ukraine. He has continued to insist that Kyiv has supported every serious effort to end the conflict while defending its right to resist Russian attacks.
The latest dispute follows an earlier confrontation in the White House in February 2025, when US military assistance and intelligence cooperation were temporarily suspended. While that crisis was eventually eased, the relationship has remained fragile.
Military support and intelligence sharing under scrutiny
One of the most urgent concerns for Ukraine is access to Patriot air-defence missiles. The systems are crucial for protecting Ukrainian cities from Russian ballistic missiles, but global shortages have limited supplies. Reports cited in the source article suggested that only a small number of interceptors remained available to Ukraine, although the claims had not been confirmed by US officials.
Kyiv has also raised questions about intelligence sharing. Zelensky said Ukraine had not received advance warnings during several ballistic missile attacks. US Secretary of State Marco Rubio denied that intelligence cooperation had been deliberately paused, attributing the reported disruption to a software problem.
Similar uncertainty surrounds Starlink satellite communications. Ukrainian officials said some terminals had experienced reduced performance, potentially making it more difficult for military units to respond to fast-moving drones. Washington has denied ordering any deliberate slowdown, but the repeated allegations highlight the lack of trust between the two governments.
Why the Russia deal has alarmed Kyiv
Ukraine was reportedly caught off guard when Trump announced an agreement intended to reopen US markets to Russian diesel. The move came as Ukrainian forces continued long-range strikes against Russian oil infrastructure, and analysts viewed it as a possible signal that Washington was unhappy with Kyiv’s strategy.
Trump also waived a range of sanctions on Russia shortly before they were due to take effect. The US president argued that the measures could complicate peace negotiations. For Ukraine and its supporters, however, the decision appeared to offer concessions to Moscow while applying pressure to Kyiv.
Oslo talks offer limited hope for diplomacy
Despite the strained relationship, the Oslo discussions produced some cautious optimism. Witkoff is expected to take updated proposals to St Petersburg, where the response from Russian President Vladimir Putin will be closely watched.
Norwegian Prime Minister Jonas Gahr Støre said the discussions had helped clarify several issues. Zelensky also indicated that conversations with the US secretary of state had been productive and suggested that concerns over early-warning intelligence might already have been addressed.
He expressed hope for progress on Patriot missile supplies and Starlink access. Nevertheless, the broader political disagreement remains unresolved. The United States appears to be pushing for a diplomatic settlement, while Ukraine fears that pressure to negotiate could weaken its security and leave Russia rewarded for its aggression.

What happens next in the Ukraine war?
The immediate focus will be on whether US and Ukrainian officials can restore confidence over intelligence, air defence and communications. The next stage of discussions with Russia may also reveal whether Washington’s diplomatic approach can produce meaningful negotiations.
For now, the public optimism surrounding the Oslo meeting has not erased the central problem: Trump and Zelensky remain divided over military strategy, relations with Moscow and the conditions for peace. Their partnership is essential to Ukraine’s defence, but it remains vulnerable to sudden political shifts.
