Ukraine's President Volodymyr Zelenskyy called into question the U.S.' commitment to its allies in Europe. Zelenskyy said President Donald Trump's first act as president — the signing of a raft of executive orders on a raft of domestic issues — suggested his administration would not be overly concerned with Europe's future.

Trump's election win in November had sparked hope of a diplomatic resolution to end Moscow's invasion of Ukraine that began in Feb. 2022, but it also led to fears in Kyiv that a quick peace deal could come at a high price for Ukraine.
