"I want him to stop Iran from acquiring nukes by any means "necessary."
Oh yes, the Iranain nukes. We can't go around trying to stop every soverign state that wants to develop WMDs from doing so. What would you have Dubya do, use atomic weapons to stop Iran's nuclear program? The important stuff is pretty heavily reinforced if I recall. Maybe we can invade Iran. That worked really well in Iraq didn't it. The solutions are politically impossible. That is why a strong nuclear deterrent and a missile defense program is so important. Besides, what nation with a handful of nukes (and no long-range delivery system) is going to use them against a nation with thousands of both.
The biggest worry here is that IRAN is not a rational state and deternce may not work. There are people in IRAN that would be glad to launch a nuclear jihad and sacrifise their popluation.
Here is Akbar Hashemi Rafsanjani famous quote, one of Iran's top leaders:
"If a day comes when the world of Islam is duly equipped with the arms Israel has in its possession, the strategy of colonialism would face a stalemate because application of an atomic bomb would not leave anything in Israel but the same thing would just produce damages in the Muslim world", Former Iranian President Akbar Hashemi Rafsanjani told the crowd at the traditional Friday prayers in Tehran.
By damage he means 75 million people in Iran versus serveral billion muslims around the world.
Another concern is that they will transfer nuclear weapons and materials to their terrorist agents in other parts of the world as they do with conventional weapons today.
