George H.W. Bush faced several foreign policy challenges as the first president after the Cold War. He sent troops to invade Panama and remove dictator Manuel Noriega. He also authorized Operation Desert Storm to expel Iraqi forces from Kuwait after Saddam Hussein invaded. This military operation involved five weeks of aerial bombardment followed by a ground invasion that forced Iraq to withdraw from Kuwait within 100 hours and agree to a UN ceasefire. Bush was reluctant to intervene in conflicts in China and Yugoslavia but sent troops to Somalia to deliver humanitarian aid.
