That is where the oil is
Oil was first discovered in Southwest Asia in 1908. Since then, oil fields in many regions of Southwest Asia have been found, and other countries rely heavily on Southwest Asia for oil to meet the demands of their economies: transportation requires gasoline (which is oil in a refined form) and power plants burn oil to produce electricity. Specifically, the United States, Japan, and many European countries heavily depend on Southwest Asia for oil because it is home to such vast amounts of petroleum. So, Southwest Asia's oil fields are important to many countries' economies, and thus the world economy, making Southwest Asia very important in terms of world position.
