If you go by silly progressive spin, (kinda like present day "tax cuts" where everyone's taxes are staying the same) then sure it was a folly.
If you go by what was actually said and the intelligence it was based upon, then no.
As I've said before, I stand by the decision to invade. I don't stand by the cost in lives. While it should have been handled completely differently, I still believe it was a situation that needed to be handled.
