President Donald Trump issued a rare rebuke of Russian President Vladimir Putin after Russia launched a major attack on Ukraine overnight. He later said he believed Putin would listen to his plea to halt Russian strikes on Ukraine and expressed optimism about a potential peace deal.

During his campaign, Donald Trump said repeatedly that he would be able to end the war between Russia and Ukraine “in 24 hours” upon taking office.

President Trump’s inability to halt the war in Ukraine after promising to do so quickly has left him increasingly frustrated. The question now is whether he is willing to press Moscow for concessions to get a deal.
