There are a lot of interesting historical factors that led to the destabilization of the region: 1. After World War II, the entire region turned anticolonial and Arab independence movements took off in every country. Some of these efforts were thwarted by the US and Britain, as in the crushing of the pro-democracy government in Iran and the installation of the puppet Shah, and some were far more successful, as with Nasser's Egyptian government. 2. The CIA got in bed with the Egyptian Muslim Brotherhood in the 1950s after France and Britain were ejected from their colonial holdings in the region (see Suez Canal Crisis, c. 1954) because radical Islamic fundamentalism was viewed by the CIA as a reliable bulwark against the Godless Communist Soviets in the battle for control of the Middle East and North Africa (and more importantly, of their extensive oilfields). A major motivation for this was Egypt's Nasser reaching out to the Soviet Union for support. 3. A quick-and-dirty summary is that Western powers who wanted to retain control of the region turned to a colonial standard, divide-and-conquer, to break up Arab independence movements and install puppet regimes beholden to Washington and Wall Street. At the same time, the Soviet Union engaged in similar behavior and thus the whole region turned into a Cold War proxy conflict zone, with control of the oilfields being the ultimate prize.
