The United States is selling weapons to its NATO allies in Europe so they can provide them to Ukraine as it struggles to fend off a recent escalation in Russia’s drone and missile attacks, President Donald Trump and his chief diplomat said.

If the plan is finalized, it would allow critical aid to flow to Ukraine as it endures one of Russia’s heaviest assaults of the war.

U.S. military and NATO officials are discussing a possible plan that could be unveiled in the coming days to provide Ukraine with much-needed aerial defense weapons.
