President Donald Trump predicted Monday that European allies would bear the brunt of responsibility providing Ukraine certain security guarantees to prevent Russian aggression, but that the U.S. would also help them. Trump’s comments come as Ukrainian President Volodymyr Zelenskyy, along with other European leaders, visited Washington, D.C., to advance peace talks to end the war in Ukraine just days after Trump met with Russian President Vladimir Putin . "President Putin agreed that Russia would accept security guarantees for Ukraine. And this is one of the key points that we need to consider," Trump said Monday during a meeting with European leaders at the White House. "And, we're going to be considering that at the table. Also, like who will do what? Essentially, I'm optimistic that collectively we can reach an agreement that would deter any future aggression against Ukraine."
