The Iraq War: Legal or Illegal?

Pinky wants some answers: Is the U.S.-led invasion and occupation of Iraq legal or illegal? Do any of the charges of illegality we've been hearing about have any legal basis at all? And why should we even care about international law anyway? Pinky and friends do the research and then tell you all the answers!
