Obama: We Made Ourselves Vulnerable Former US President: As a former president, I can say that sometimes there are factors beyond the president's control that ultimately cause the best laid plans to fail. You may have a good plan, but something unexpected happens. However, this did not happen here. We curbed Iran's nuclear program. I implemented an agreement that everyone knew would have prevented Iran from obtaining nuclear weapons. I didn't have to fire a single rocket; I used diplomacy. As a result of this war, Iran has veto rights over shipping in the Strait of Hormuz.
