There are a lot of matters here to discuss, so I don't really have the zeal to post all of my "positions" on them.
Position #1
I don't think invading Iraq is nessisary or desireable from a stratigic point of view. They might have WMD, but I have not heard of reports saying that they have any feasable way of getting them here. We have ICBMs and stealth bombers. We have all the bombs! H-bombs and A-bombs! (I think I stated this earlier)
Position #2
If Iraq or any other country invited us to a nuclear exchange, I would feel ablidged, civis americas sum, to join them. Since that option is foolish for a petty dictator like Sodom, I say BRING IT ON! WMD? For sodom, it would be weapons of certain destruction.
Position #3
If we were actually hit by a decapitative blow then things would be in chaos. All bets would be officially off. And I think this last position is certainly up for debate!
