Guest from NW, I agree pretty much with everything you are saying, except for the final paragraph. I'll be voting for Nader. You said:

"geographically, tactically, culturally, of course it is not like vietnam."

Which is the reason why I'm arguing against using it as an analogy to undermine and defeat Bush. It doesn't take much thought by the pro-Bush and pro-war Democrats to use the fact you stated so well above, and turn it against those of us on the anti-war side. I think it is a poor choice tactically, and I wish Kennedy hadn't made the speech invoking it.
