Hussein started two wars, invaded one country (Kuwait), helped abet terrorism by sending money to foreign terrorists, set up terrorist training camps in Iraq, harbored terrorists, stored WMD materials, created WMDS, and slaughtered his enemies and the Kurds at times using WMDS. He murdered approx. million of his own citizens, and tried to have the first Bush prez assassinated. But he deserved to stay in power says Nixon.
Here is another thing people don't talk much about. If not deposed, Hussein would be turning 80 next year. Maybe he's healthy, but maybe he's dead from natural causes or too sick to assume power. His murderous sons would probably be in charge, and they're more in cahoots with Al Qaeda than his pappy. Al Qaeda would have a gigantic terrorist base from which to launch operations and vast oil wealth with which to do it. Just like Saddam Hussein did.
