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.

Speaking to Europe’s elites at the World Economic Forum in Davos, Zelensky laid into many of the European countries that have helped keep Ukraine afloat since the Russian invasion, chiding them for not taking their own defense and the threat from Moscow sufficiently seriously.

Volodymyr Zelensky has warned European leaders Donald Trump will ignore them if the continent doesn’t take better care of its own defences.

Speaking a day after Trump’s inauguration, Ukraine’s president told world leaders at Davos that Europe needs to remain united and “learn how to take care of itself.”
