Look at recent history. In 2003 Iraq’s government had no nuclear weapons (or other WMD). The U.S. government invaded, and before long Iraqi President Saddam Hussein was hanging from a rope. In 2011 Libya’s government had no nuclear weapons. The U.S. government led NATO on a bombing campaign to help a group of rebels, and before long Libyan Col. Muammar Qaddafi lay dead on a roadside. Today Syria has no nuclear weapons. The U.S. government and NATO are currently aiding rebels seeking to overthrow (and likely kill) President Bashar al-Assad.
