Mossad vs. Mousavi

There are lots of unknowns about the Iranian nuclear program. But a few things are certain.

First, Israel cannot destroy Iran's nuclear capabilities with a single targeted strike. This is not another Osirak. Any offensive would be complicated, risky, and likely to fail.

It would also provoke a massive regional conflagration. The Sunni old guard -- Egypt, Jordan, Saudi Arabia -- might not complain, but Hizballah and Hamas will attack Israel, and the Iranian-backed Syrian regime could also retaliate.

In other words: A successful attack on Iran's nuclear facilities is highly unlikely.

Given that, we know Iran will eventually have the capacity to build a nuclear bomb. We don't know if they'll actually build one -- but they certainly will have the capability to build one within the next five years.

And that begs the question: Who do you want as the president of a nuclear-armed Iran? A childish hard-liner like Ahmadinejad? Or someone more moderate -- someone who represents the millions of Iranians protesting in the streets right now, most of whom probably do not want a nuclear confrontation with Israel?
