The United States would not recognize a referendum by Crimea to leave Ukraine, and a shift of that region to Russia "is not a done deal," a top Obama administration official said Sunday. "If there is a referendum and it votes to move Crimea out of Ukraine and to Russia, we won't recognize it and most of the world won't either," deputy national security advisor Tony Blinken said on NBC's "Meet the Press." "Were that to happen, the isolation of Russia, the cost that it would pay, would increase significantly from where they are now," he said. Russia has shown no signs of backing down over the Crimea crisis in the face of economic sanctions from the U.S. and its European allies.
