The United States may soon be at war in the Middle East — again! President Trump is weighing whether to attack Iran, although neither he nor any administration official has bothered to fully explain why.

The Cato Institute's Justin Logan takes us inside the "imperial presidency." Justin Logan is the director of defense and foreign policy studies at the Cato Institute. He is an expert on U.S. grand strategy, international relations theory, and American foreign policy.
