WASHINGTON/munich, Feb. 16 -- Ukraine has little chance of surviving Russia's assault without US support, President Volodymyr Zelensky said on Friday after phone calls this week by US President Donald Trump with Zelensky and Russian President Vladimir Putin. "Probably it will be very, very, very difficult. And of course, in all the difficult situations, you have a chance. But we will have low chance - low chance to survive without support of the United States," Zelensky said in an interview on the NBC News program "Meet the Press"....
