Answer:
protect Saudi Arabia and Kuwait against Iraq
Step-by-step explanation:
In 1991, Iraq led by Saddam Hussein, decided to attack Kuwait. There were two reasons for this. One was that Saddam Hussein thought that Kuwait belongs to Iraq, and the other was the large oil reserves. The Iraqi military moved and invaded Kuwait without any problem, and it also had its sights on Saudi Arabia. This rang the alarm in the US and the UN, as they didn't wanted the majority of the oil reserves to be in the hands of the Iraqi dictator. The US and the UN sent their troops in Kuwait in order to push back the Iraqis, and they managed to do it, liberating Kuwait, and securing Saudi Arabia from Iraqi invasion.
