It's very important for people to realize that the McCain-Palin ticket is explicitly running on war against Iran. If McCain-Palin is elected, there will be war. If Obama-Biden is elected, there is a tiny chance there won't be. In terms of the future, this is the critical issue to be decided. Someone - probably Scheuneman - wrote Palin's op-ed/speech on this. It could not be clearer:
"We gather here today to highlight the Iranian dictator's intentions and to call for action to thwart him. He must be stopped. The world must awake to the threat this man poses to all of us."
She and/or McCain will launch a pre-emptive strike on Iran. This much we know. It isn't a matter of if but when. For McCain, it is a matter of fighting wars to win, instead of accepting any limits on American power. For Palin, it is a matter of theological destiny. For Americans, it may be a decision about whether America will start a Third World War or try to prevent it.
