Oh...I don't care to get involved with your arguments with the Kazz. That's like talking to a brick wall.
I don't know if we entered the Iraq war illegally; we did, however, enter it in violation of the UN Charter.
The United Nations Charter "prohibits the use of military force against any member nation without the approval of the Security Council", but lacking the required authorization, Bush decided to attack Iraq asserting that Congress gave him the authorization to do so by approving House Joint Resolution 114, the "Authorization to Use Military Force".
