it's no wonder the US state department and its clients have obsessively kept the region shattered for 75 years
The British I maintain were doing this before them for at least another 40 years prior based on lessons learned in subjugating India. And I believe worked hand in hand with the US to construct the modern middle east and "moderate rebels" as well as the various corrupt kings and fragmented islamist movements.
Exploiting existing ethnic or other tensions to play groups off each other to keep a nation divided so you can conquer them with your own forces and significant amounts of proxies from these groups. Pioneered by the British in India hundreds of years ago, still working today in tons of places and a favored strat of the US from Yugoslavia to China (Xinjiang, Tibet, Hong Kong), to Russia and therefore likely a strat their regional outpost has taken note of.
