Why were world leaders concerned about saddam hussein gaining control of middle east oil?

The middle east economy depended on oil to survive, and because most of the countries around the world need oil one way or another, they usually bought from the Middle eastern Countries that were rich in it. When Saddam Hussein took control of the oil, it meant that the legal governments could not use them, which helped drop the amount of oil they could sale and raised gas prices. In this way, the middle eastern countries lost money
