Yeah well his individual actions (and those of his close friends/staff/etc) were most definetly evil, the majority of his population (excluding those that were being brutally persecute for obscure crimes... and his soccer team if you heard about that) were doing fine. I'm not in any way endorsing his actions, but the way most of the country lived was close to normal considering what life may have been in other parts of the region.
In terms of the actual invasion, I completely disagree with nearly everything that was fed to the public about the conflict, and the conflict altogether. IMO, Afghanistan was at least justified, "If you crash our own planes into our buildings, we WILL come over there and rip the turbans off you extremist bastards", I totally agree. But two wars on the same hand is something I believe is a huge tactical mistake. We only WANT Bin Laden, there isn't a lot we can do about the Paki's, and no-one has given us an invite to come and send the Middle East on a backward Spiral, yet it happened anyway
