Ukrainian Interior Minister Arsen Avakov called Republican presidential candidate Donald Trump's claim that Crimea wanted to be annexed by Russia in 2014 evidence that he is "a dangerous fringe politician." Former Ukrainian Prime Minister Arseniy Yatsenyuk said it was "a breach of moral and civilized principles." And Ukrainian ambassador to Washington Valeriy Chaly told Foreign Policy in an email on August 1 that the businessman's comments raised concern in Kyiv, especially if they could lead to a dramatic shift in U.S. policy.
