I hate seeing pictures like that, but that's what war is. Yes it's a definate reality check, one of my friends is over there right now and everytime I see a picture like that, sorta gets me nervous.
I don't want to get into a huge debate, but remember how many countries hate us over in the middle east. Then think of how many countries would 'work' with Saddam in exchange for things. These countries that are 'working' with Saddam or did work, also gave him the chance to move and hide weapons in other countries.
Think of it this way, when you were a kid and had like $5, you would try to hide it maybe in a secret place. Then how about your brother finds out you have $5 and begins to look for it. So what do you do, you try to either get rid of that $5 before he can take it or hide it somewhere he'll never look.
In no way am I saying I am correct and you are wrong, or I'm wrong and you're correct. I'm just trying to say theres always a possibility the weapons have been moved, even a possibility they never existed. But after some reports of radiation found in a river in Iraq and the jet fighter planes found buried in the desert, anything is possible.
