The US and Israel are also major players in the destruction of the Middle East. If you could turn back the clock and eliminate those three nations' influence from the region, current history would change very much for the better though other nations may have entered the void.
Inevitably when powerful nations spend a lot of time brutalizing weaker nations a lot of bad will happen. A more extreme case was Cambodia after Nixon bombed the shit out of that nation. It allowed the Khmer Rouge to gain power. The Khmer Rouge was a small movement that would never have taken control without the mass slaughter and destruction of farm lands by the US.
Much of the Middle East had a diverse population, and some still has, that has managed to mostly get along for centuries. Why did they suddenly fall apart when the US started supporting and arming brutal leaders and religious kooks, and overthrowing secular leaders? Is that just a coincidence? Obviously it isn't a coincidence.
