Some pundits argue that if Governor Walker were to terminate the Iran deal on day one, the Iranians would respond by kicking out the inspectors and sprinting for the bomb. That, too, is a misreading of how the world works. If the Iranians see that the new president is resolute and prepared to follow through on his threats, fear of consequences will make them less rather than more aggressive.

We have seen this before. In 1980, the American people elected a president with a reputation for resolve and on day one of Ronald Reagan’s presidency, literally as he took the oath of office, the Iranians released the hostages that they had been holding prisoner for 444 days. The time to show leadership on Iran is now, not after one gets settled into the position.

As Governor Walker said in a press gaggle this weekend in Iowa, “I believe that a president shouldn’t wait to act until they put a cabinet together or for a certain period of time… I’m going to be prepared to be president on day one.”
