President Joe Biden has arrived in the United Kingdom for the first stop of his three-nation European tour. During his visit, he will meet with King Charles III and Prime Minister Boris Johnson to discuss the war in Ukraine and the U.S.'s moral obligation to provide Ukraine with the necessary resources to protect itself. Biden will then travel to Geneva, Switzerland to meet with Russian President Vladimir Putin to make it clear that the U.S. will not stand idly by in the face of Russian aggression.
