The emerging nuclear deal with Iran is indefensible. The White House knows it. That is why President Obama does not want to subject an agreement to congressional approval, why critics of the deal are dismissed as warmongers, and why the president, his secretary of state, and his national security adviser have spent several weeks demonizing the prime minister of Israel for having the temerity to accept an invitation by the U.S. Congress to deliver a speech on a subject of existential import for his small country. These tactics distract public attention. They turn a subject of enormous significance to American foreign policy into a petty personal drama. They prevent us from discussing what America is about to give away.
