The world depended on Kuwait for oil

Explanation:

Even though Kuwait is a very small country, it has very large reserves of oil. The percentage of the world's oil reserves in the period when Kuwait was attacked by Iraq were much greater than today, as lot of the oil reserves were still not discovered. This made it even more important that the country is protected. If Iraq invaded this country and gained control over the oil reserves, there were going to be big consequences globally, so the US was quick to react. The US sent lot of troops, as well its allies, and a war with Iraq started. The war was successful, as the Iraqis were pushed out of Kuwait, and the small country was free again, and its oil reserves secured.
