Ukrainian President Volodymyr Zelensky and U.S. Defense Secretary Lloyd Austin used their final meeting Thursday to press the incoming Trump administration not to give up on Kyiv's fight, with Austin warning that to cease military support now "will only invite more aggression, chaos and war."

"We've come such a long way that it would honestly be crazy to drop the ball now and not keep building on the defense coalitions we've created," Zelensky said. "No matter what's going on in the world, everyone wants to feel sure that their country will not just be erased off the map."
