I've liven in Pakistan, Japan, Korea, Thailand, Brussels, France and England. There goes your first theory out the window.
We're not in this just to protect ourselves. Who was there to protect the Kurds when Saddam used mustard gas on them? We are doing this to protect innocent people from the drastic outlashings of an insane tyrant. A person who is known to have a desire to kill many amounts of people and who has done so in the past. It does not matter if they are American, or British, or Kurdish. They are living beings who's given rights to life are being threatened by a ruthless dictator. It's unfortunate that some innocent people may fall casualty, it would be even more unfortunate if nothing was done and Saddam killed even more innocent people.
How about the 60,000 children that starve to death each year because Saddam is taking the money that is supposed to buy them food and spending it on weapons? That's right, the money that is supposed to feed the children of Iraq is being given to France and Germany for military weapons.
But hey, it's your right to be ignorant if you want to.
Isn't life grand with these rose colored glasses?
