It's no different than the Bush administration claiming they're going to topple Saddam Hussein because of what he's doing to his own people. The U.S. really couldn't care less...unless there was something else they wanted or another angle to it. And claiming that Saddam had something to do with 9/11 was another crock of shit when they had solid intelligence that he had no connection to it whatsoever.
For the record, Saddam was knocked off because Iraq was providing support for international terrorism (including some of the 9/11 hijackers), had been flaunting the cease fire agreement from the first Gulf War practically from Day One, and was actively seeking to reactivate his WMD programs
(NOT THAT HE HAD THE WEAPONS!). Just ask the Kurds about what Saddam was like when he had WMD in his arsenal. If those programs became active again, it would've been a simple matter to hand off a particularly nasty weapon to, oh, say, Hamas, and, y'know, see what happened.
Imagine 9/11 with a small nuke on one of those planes.
Sorry, but the days of waiting until
after the attack are long gone.
Rant over. We now return you to this week's episode of "Star Trek", already in progress.
