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.

President Donald Trump told NBC he struck a deal with NATO on Thursday for the US to send weapons to Ukraine through the alliance, and that NATO will pay for those weapons “a hundred percent.”
