You have to stop asking these questions. It sort of goes with 'the smoking gun might be a mushroom cloud'. Or the Iraq people 'will welcome us because we only wanted to get rid of Saddam because he was killing his own people.' You are supposed to be keep repeating and repeating these things not questioning them. Get with the program.
Hey, what do you expect from the dimwit like me? :) I was always slow to follow and absorb the official version of the events, especially that it keeps changing.
