You think we have been paying paintball games over there for the last 50 years?
For starters, for what were at the time judged valid strategic reasons the US backed one group of murderous thugs - the Iraqi Bathes - against another murderous group of thugs - the Iranian Mullahs.
While these guys were re-enacted WWI (complete with suicidal mass infantry charges and poison gas), we were providing a half dozen kinds of covert backing to "our" side to counter assistance provided to "their" side everyone involved has blood on their hands, up to their elbows.
This was bi-partisan policy, and we would probably do the same today.
But it wasn't pretty, and a lot of reputations - and some careers - would likely suffer if the story was examined in detail.
I was in and around and [Thank God] out of Iraq more than 60 times [And Teheran and other parts of Iran a score or so times] during the 8 years of the Iraq Iran War and can categorically state from my experience that your claim the United States backed one group of murderous thugs - the Iraqi [Ba'ath Party] - against another murderous group of thugs - the Iranian Mullahs" grossly misrepresents the truth.
You have, in any case, between posts, altered your argument from the ridiculous cause of my initial response, that careful "examination of his regime's history would reveal a lot of very embarrassing material about its relationship with Western governments, including both Democratic and Republican administrations in the US," to now suggest that America was responsible for the atrocities on both sides of that conflict.
And that there are, in the United States [Given your implication] "hundreds if not thousands of businesses and individuals who have a vested interest is seeing that he's tried and convicted for a narrow subset of the crimes he committed - and that he takes the rest of his secrets to the grave."
Had you confined your allegations to the likes of France and Germany and Russia and China and some others they had a whiff of truth but insofar as your employment of the well-flogged canard that the United states of America had involvement in and must take responsibility for any part of Sadam's bastardry, I will very comfortably stand by my first reponse to your first post.
And you really aught ponder my suggestion that Joseph Gobbels seems alive and well and lives in your mirror and that correlation is not causation.
