That fact does not make your opinion any more legitimate than others who are also informed about current events. I know someone whose father got out of one of the buildings on 9/11. This person doesn't think we did the right thing in going into Iraq. There are other 9/11 survivors who also feel the same way. Do their opinions trump yours because they survived an even bigger attack than the one you did? Of course not. The breakdown of opinion among survivors is probably in sync witht the general population.
I survived both attacks, not just the first. But I make no claim that that makes my opinion any better than any other. I am saying the events themselves are proof of an enemy who is determined and not containable. There is no option not to fight them. The only option is where we fight them. The various tyrants of the Islamic world are many heads of the same hydra, and we do not have the option not to confront them all. Given the nature of the particular hydra head named Saddam, we had no other option than to invade and depose him.
