In the 1980s, Saudi Arabia spent $25 billion in support of Saddam Hussein in the Iran–Iraq War. However, Saudi Arabia condemned the Iraqi invasion of Kuwait in 1990 and asked the US to intervene. King Fahd allowed American and coalition troops to be stationed in Saudi Arabia. He invited the Kuwaiti government and many of its citizens to stay in Saudi Arabia, but expelled citizens of Yemen and Jordan because of their governments' support of Iraq. In 1991, Saudi Arabian forces were involved both in bombing raids on Iraq and in the land invasion that helped to liberate Kuwait.
