Barack Obama on Iran: Trump decided to start an unnecessary war that no one asked for and no one voted for. The original rationale was, we are going to go in there and make them give up their nuclear program, their nuclear weapons. Now, the point was that Iran did not have nuclear weapons. Because I prepared a deal that everyone recognized that prevented them from acquiring nuclear material. And I didn't have to fire a missile to do that; I simply needed to engage in diplomacy.
