Saber-rattling is not a good way to get the Iranians to cooperate. But it is a good way to start a new war — a war that would be a disaster for the Middle East, for the United States and for the world. A war that, furthermore, would destroy what little remains of U.S. credibility in the community of nations.
A better approach would be for the United States to engage directly with the Iranians and to lead a global diplomatic offensive to prevent them from building nuclear weapons. We need tough, direct negotiations, not just with Iran but also with our allies, especially Russia, to get them to support us in presenting Iran with credible carrots and sticks.
I don’t know what kind of campaign strategy this is, but maybe he can be Secretary of State or some kind of special envoy.
