Yes, either you or I might die tomorrow morning. Hit by a bus, killed by a jealous lover.. you just never know, do you?

The posters aren't as polarized as you think, IMO. I know, for example, that a lot of the US guys I disagree with here on this BBS would receive my instant support if they or theirs were threatened. We may argue and fight viciously between ourselves, but we also band together for the common good easily and quickly. 9/11 highlighted that aspect of our society as well.
I do think there's a clear split between those that, for whatever reason, can't bring themselves to see the US as anything other than stupid, evil, imperialistic or a combination of all three. There's some people here that would choke if they had to let a good word about the US slip out of their throats.
No longer friends? Well, my dad always said "tell me who your friends are and I'll tell you who and what you are".
So, if folks that would rather champion and defend mass murderers and Islamic lunatics don't like us and are not our "friends" ...... if folks that can only point out the mistakes we've made while ignoring the good we do and excusing the atrocities committed by the people we now oppose...........well, that's a good thing in my book.
I wouldn't want have that sort of "friend".
I'm sure you think you've been mostly right. Heck, it took a multitude of posts to get you to admit you were totally wrong about Libya and the NPT and that's a clear cut black and white issue. So, I'm sure you think you're "mostly right" about anything else. Be advised...... you'd get disagreement there too. You might even get "ganged".
Yeah, my countrymen are dying. You bet. I don't like it a bit.
And, whether YOU like to believe it or not, their sacrifice may well have been the key factor in removing WMD from Libya. Only a lunatic would think that's not a good thing.
And the Libyan change of heart my in turn cause Iran to re-think it's position. You realize the UN/IAEA has a sneaking suspicion that Iran is violating the NPT as well, don't you?
Bottom line is, my countrymen are trying. Pretty clear where their thumbs are and where their thumbs aren't.
