The U.S. is deploying more of our (potentially now ineffective) missile defense systems in places where we had promised not to do so. The Iran deal is dead. Nationalism is on the rise everywhere, and nuclear states like Pakistan, India, and China are not immune. The world is at greater risk now than at any point since the Cold War.
