A common historical and geo-political error is to view cultures or movements in monolithic categories or terms. By oversimplifying there is a tendency toward sweeping generalization, wrong questions, and the obvious wrong answers.
In Cold War era geo-politics the most poignant example of this can be found in the Western assessment and interpretation of Communism. Only after the Sino-Soviet Split and a bit of reflection regarding Vietnam did American policymakers and advisors begin to grasp their error. Sadly the Korean and Vietnam Wars had already happened. But even the wisdom gained by the 1970's played out in Détente and Realpolitik was abandoned by the Reagan White House in the 1980's. Conservatives with their tendency to simplify the message, marketing ideological soundbites, in the end won the day, and right up until the end of the USSR, most Americans believed they had God on their side in the war against the Evil Empire. While no one laments the fall of that or any Evil Empire, those who claimed and still claim to have God on their side have learned nothing, and march on in blind ignorance, regardless of the domestic and international costs of their Sacralist wars and worldview.
If Orwell taught us that Power needs an enemy to help manipulate the masses, then when Soviet backed Communism fell we should have expected a new enemy to appear shortly thereafter. Those wielding Western Power needed a justification to continue expanding, and leaders have long known that fear is a powerful tool to help them to that end. It creates a malleable public practically begging the State to expand.
