Hindsight is an historical judgment. Personally, during the run up to war, I was conflicted & people were trying to get me to jump on the “invade Iraq now” train. I thought it a better idea to, not empty the chamber on a non-target &, instead, hit Iran. Which, even then, was known to actually have a valid nuclear program & well-documented aspirations. Also; Iran was & is our enemy.
But, thinking back, there was a lot of folderol going on with Iraq. Saddam was abusive, he enraged people by detaining American children, his genocidal actions were documented, he did attempt to assassinate Bush Senior, our CIA had “intelligence” of wmd’s & there was the very, very real blood-lust after 9/11.
Ask any non-American that can remember & they’ll tell you the US march to war was palpable & frightening. It had a life of its own.
