It is both an outgrowth of UK and US directly funding and supporting Muslim extremism to divide opposition to colonialism/imperialism since Jews, Christians, and leftists would be alienated and the rally around the flag type of effect of using already at-hand identity markers to opposed invaders and oppressors. The entire cold war was the US and sometimes their vassals like Saudi Arabia funding and supporting Islamism, as a counterweight to secular leftist forms of anti-colonialism, which they were actively suppressing, because of its incompatibility with socialism/communism.
Most easy and obvious examples is the Mujaheddin, aka proto-Al Qaeda and Taliban precursor. And Israel supporting Hamas over the PLO since the PLO was a secular organization that appealed to human rights.
I am not too active here, but much thanks! I really like your administration and site!
