Let’s say this slowly: the Bush administration wanted to use 9/11 as a pretext to invade Iraq, even though Iraq had nothing to do with 9/11. So it tortured people to make them confess to the nonexistent link.

True, and very serious. I have nothing serious to add, but in the spirit of not publishing posts in which I just quote other people, I'll note that “it's evil” is not one word and that his post is therefore mis-punctuated. It should either not include the “it's” after the colon, or not use a colon there at all.
