That's plausible but from what I've read not been confirmed. The stronger proof is Yasin vamoosing back to Baghdad after the first 9/11 bombing. No one seems to pay attention to this glaring fact. Let's restate that: an Iraqi citizen was deeply connected to the first WTC radical/Islamo bombing and was given shelter in Baghdad by Hussein. And doubters wonder why some people believed Hussein was involved with the second bombing. Well it's because it was very logical to assume that he was involved. With the first and second bombings.
And again there is a lot of smoke concerning Iraqi agents meeting with Al-Qaeda. Even the 9/11 commission affirmed they had connections. So why is it so hard for many people to believe that Hussein might have been more deeply involved in 9/11?
As unpleasant a mental exercise as it is, try to step into their shoes. If Hussein was involved in 9/11 and even more strongly in the 93 bombing, then Pres. Bush would have an even stronger causes belli for invading Iraq. This moron and ingenious deceiver, both contradictory descriptions of our President held by the liberals, would seem very justified in invading Iraq even by New York Time's standards. That can't happen in the liberal mindset so of all the concepts that must be resisted, Saddam's connections with the World Trade Center bombings must be resisted by the left most of all.
