CNN's Jim Sciutto on Trump's Erratic Foreign Policy Approach

In his new book "The Madman Theory," CNN anchor and Chief National Security correspondent Jim Sciutto highlights how President Trump’s unpredictable behavior--including threats to meet North Korea with “fire and fury” and to pull the U.S. out of NATO and NAFTA--have unnerved enemies and allies alike. Sciutto discusses how Trump’s volatility has led advisers to hesitate in giving the President military options because they feared he could start a war.  We'll talk to Sciutto about the lasting imprint Trump has left on the world after four years in office, and get his take on how that will shape America’s place in the world.
