"Russia's war against Ukraine is one of the biggest challenges for the United States of our time," said Joe Biden, speaking to the heads of American diplomatic missions.
He emphasized the importance of helping to protect Ukraine from Russian aggression. "If we don't do it, imagine what will happen. Think about it," the head of the White House urged the diplomats. Among the other main challenges facing the USA, Biden mentioned the competition with China, climate change, and the need to prepare for a possible new pandemic.
