Is the Department of Defense worried about our aging nuclear arsenal? This report argues Secretary Gates is.
The nature of the world has changed since the end of the Cold War. For example, there no longer remains a justification for keeping nuclear weapons in Europe. With Iran I am an advocate of the "Godfather" strategy. Think about the "peace conference" scene in the original Godfather. Don Corleone says that he will make peace, but he needs to make arrangements to get his son Michael home from his Sicilian exile. Corleone says that he is a superstitious man, and that if Michael is "hit by a bolt of lightening" he will blame some of the people in the room.
Our policy with Iran should be similar Yes I agree, try to cut off imports of items which can be used for their nuclear program, but otherwise explain the Godfather strategy. Make it clear that if Hamas or some other group gets hold of a nuclear weapon, we may blame Iran. This hopefully will motivate them to make sure no one decides to freelance nuclear strategy.
