Explanation:

The Middle East, as a region, has been blessed with reserves of oil. This is the natural resource for which there is the highest demand on the global market, so having it means that it brings a lot of benefits. The most obvious benefit is a lot of profit, but there is also the political influence because of the dependence of other countries on the resource.
