While I respect service to the efforts of WWII, I disagree with your above statement! Hilter WAS PURE EVIL RUN AMOK! His actions, and those of his followers laid the ground work for this horrible Military Action against (a German City) Dresden.
The destruction of the WTC was exactly the same as the destruction of Dresden and the massacre of it's citizens...not a particle of difference. The aim was to kill civilians.
Hitler was evil, you say, and that was enough to justify the Dresden massacre....OK, OBL is evil and, using your logic, that justifies the WTC disaster!!!....I don't think so.
