McCain is committed to it if Tehran gets nuclear weapon capacity. Frm Sixty Minutes:

Pelley: Would it be your policy in your administration to engage in preemptive war against a country that might pose a threat to the United States a country that hasn't attacked us.

McCain: If it's a provable direct threat. Suppose that the Iranians had nuclear weapons. And you had a whole lot of other information about Iranian intentions and you could make the case to the American people and to the world, I think it's obvious that we would have to prevent what we're absolutely certain is a direct threat to the lives of the American people.

Remember that McCain believed that Iraq was a "provable direct threat." It also seems relevant to me to ask if the direct threat is to Israel or to the United States. There is a difference, however much it seems at times as if many Washington do not think so.
