After stops in New York and Washington, where there were signs of fatigue about the war, Ukrainian President Volodymyr Zelenskyy was looking to Canada for reassurance during a visit on Friday. Prime Minister Justin Trudeau told Zelenskyy that Canada would stand by Ukraine for however long it takes. David Akin reports. In Washington on Thursday, Zelenskyy got another commitment for $325 million in U.S. military aid including some long-range missiles that can strike targets 290 km away. Without long-range missiles supplied by the U.S. and the U.K., Ukraine could not launch counterattacks against Russian positions. Eric Sorensen looks at the challenges Ukraine is up against.
