Sen. John Barrasso urged the U.S. and NATO to take stronger action in response to Russian aggression toward Ukraine.He suggested the U.S. send ships to the Black Sea, and encouraged NATO to do the same in a show of force against Russia. He also suggested providing additional anti-aircraft and anti-ship weaponry to Ukraine.

"Putin respects strength and action. He will not stop until he is stopped. He can smell fear, and that’s the way he acts," said Barrasso.
