Doomsday Scenario?

Disclaimer: I don’t really believe what I’m about to say.

After a Long Island Iced Tea last night I discussed this with my friends: a possible doomsday scenario that seems plausible.

1) McCain becomes President
2) McCain goes to war with Iran
3) Russia sends aid to Iran
4) USA receives aid from France, UK, and Israel
5) Having received aid from Israel, Arab countries line up to defend Iran
6) Now needing aid, China agrees to support Russia on specific conditions.
7) America loses and resorts to nuclear weaponry.
8) Russia uses nuclear weaponry.
9) Radiation is a b*tch.

So that’s my liquor induced theory and most notably the ramblings of a non-sober man. But any thoughts on the likelihood of this? What’s your theory about how things will go down between now and 2012.
