Ukrainian President Volodymyr Zelensky stated that he held a “very important and useful” call with U.S. President Donald Trump on Friday, July 4, amid escalating Russian attacks and a controversial pause in U.S. arms shipments to Ukraine. The call came just one day after Trump spoke with Russian President Vladimir Putin, a conversation Trump later described as “very disappointing.”
Zelensky used the call to thank Trump for U.S. support and to push for increased air defense cooperation. He said both leaders agreed to work on “strengthening protection of our skies” and to arrange meetings between their defense teams. The conversation also covered joint weapons production, drone technology, and mutual investments.

Why It Matters
The Trump administration confirmed it had frozen a shipment of air defense and precision weapons due to concerns about depleting U.S. stockpiles. The decision caught Ukrainian officials off guard, prompting urgent talks to clarify the status of future aid. Ukraine’s Defense Ministry stated that it had not received formal notice of the freeze but emphasized the need for “predictability” in defense support.
On July 4, Russia launched 539 drones and 11 missiles at Kyiv and other cities, injuring at least 23 people and damaging infrastructure across six districts. Zelensky called the attack “deliberately massive and cynical,” noting it began almost simultaneously with media reports of Trump’s call with Putin. The assault was the largest of the war and came amid reports that Russia was massing troops near the Sumy region for a potential summer offensive.
Zelensky said he and Trump agreed to work on increasing Ukraine’s air defense capabilities and to hold follow-up meetings between their teams. The two also discussed joint defense production, including drone technology, as well as mutual procurement and investment opportunities.
“We are ready for direct projects with America,” Zelensky said, calling it “extremely important for security.”
After his July 3 call with Putin, Trump told reporters he was “very disappointed” and saw “no progress” toward ending the war. Putin reportedly told Trump that Russia would not retreat from its war goals, including preventing Ukraine from joining NATO. Trump’s call with Zelensky was seen as an attempt to rebalance the optics after the Putin conversation drew criticism.
Ukrainian officials warn that Russia is preparing for a multi-front offensive and may be using the weapons pause as a signal to intensify attacks. Zelensky has urged the U.S. and allies to impose tougher sanctions and restore halted aid, warning that “without truly large-scale pressure, Russia will not change its destructive behavior.”
What People Are Saying
Zelensky in his post to Telegram, translated from Ukrainian to English: “We in Ukraine are grateful for all the support provided, which enables us to protect lives and our independence. We have achieved a great deal together with America and support all efforts to stop the killings and restore a normal, sustainable, and just peace. A dignified peace agreement is needed, and Ukraine supports the American proposals.
“Today we discussed the situation: the Russian airstrikes and, more broadly, the situation on the front lines. President Trump is very well informed—thank you for this attention to Ukraine. We discussed air defense capabilities and agreed to work on strengthening our sky protection. We also agreed on a corresponding meeting between our teams.”
What Happens Next
With Russia escalating its attacks and Trump signaling both frustration and restraint, Ukraine’s diplomatic balancing act is likely to become even more intense.
