U.S. President Joe Biden and his NATO counterparts wrapped up a two-day summit Wednesday with pledges of long-term support for Ukraine but no offer of the country's protection under the alliance's security umbrella.
Results from the meeting in Lithuania, a nation on NATO's eastern flank that borders Russia, were mixed. Ukrainian President Volodymyr Zelenskky was grateful for the pledges of more arms and ammunition but disappointed that his country has no clear time frame for joining the world's biggest security alliance.
