Ukrainian President Volodymyr Zelenskyy said Friday that it would be “very, very, very difficult” for Ukraine to survive without U.S. military support, both now as it tries to repel Russia's invasion and in the future after the war ends.

"Probably it will be very, very, very difficult. And of course, in all the difficult situations, you have a chance," Zelenskyy told NBC News' "Meet the Press" on the sidelines of the Munich Security Conference. "But we will have low chance, low chance, to survive without support of the United States. I think it’s very important, critical."
