Yeah, that's exactly what it was. Which is why we now have a military stronghold in the middle east. Yep, definitely follow you there...
The invasion of Iraq was to help PREVENT another 9/11! That's the whole point! If we waited until the Iraq terrorist groups staged another 9/11, it's too late! The fact is, they are all terrorist groups, and they are all intent upon one thing: killing innocent people. I believe, with the power that America has, it is our responsibility to terminate terrorist groups as quickly and as effectively as possible.
Now, the current operations have killed a lot of innocent people, but there's not a whole lot we can do about that. If we didn't invade, there may have been one, two, three more 9/11-type attacks. Who knows... but we cannot allow the terrorist groups to continue thriving, that will only harm us more in the long run. Can you imagine if they managed to get a nuke to hit LA? New York?
