The most accurate answer to why the United States became interested in the Middle East after World War II is:
C - to buy oil easily, protect Israel, and limit Soviet influence.
Post-World War II, the U.S. recognized the strategic importance of the Middle East, particularly due to its vast oil reserves, the establishment of Israel in 1948, and the need to counter Soviet influence during the Cold War. The U.S. sought to secure its interests in the region through diplomacy, military support, and economic partnerships.
