The Israel/Iran War Game
Why is that? Because Israel is only going to do it if they think they know that time's up. That the Iranians have everything they need to put a nuclear warhead on a serviceable missile that can hit Israel. Israel does not want to do it. For as long as I can remember, the Israelis have been trying to get U.S. to do it, because they have long believed that Iran was so big that only a big country could successfully take on the mullahs in a direct confrontation. So Israel's Iran policy has been to convince us to do whatever the Israelis think is best. And while they're willing to do their part, they are very reluctant to take on the entire burden.
Just read what Israeli leaders are saying and you'll see that, I think.
But if you're the prime minister, and your head of military intelligence comes to you and says "time's up," and you've failed to convince the Americans, then you've got to act.
Is that the situation today? I don't know, and I don't know if anyone around here -- including Petraeus and Panetta -- knows. The one thing I do know is that in order to answer the "will they or won't they?" question, you've got to know what the Israelis think they know about the Iranians.
Which you don't. Nor I. So shut up and stop sucking your thumb.
