To fully understand why we are where we are, it is very important (IMO anyway) to gauge how transactional it has always been. From the earliest invaders insisting that Christianity is the only 'right' religion, pretty much every historic incursion into non-western countries has had nothing to do with 'improving' the lives of those there and everything to do with creating either some hoped-for cultural dominance or furute marketplace. The West has never, ever understood the Middle East. It has never really tried. Instead, it has been a series of subjugate/commercially-motivated moves which have (of course) done nothing long-term other than create space for nefarious local exploiters and unrest among the people. If anyone can name an extremist group in the region which has not grown due to outside influence, I'd be interested to learn. As for the US 'withdrawing' from 'remote wars', I'd wager the only reason is that there are others to serve and that it simply does not align with enough favourable 'returns' to continue some of these. As human beings, WE see the overarching reality of failed foreign interventions, lives and cities destroyed, and antagonists emboldened; sadly, I'd guess that there have been a percentage of those at the 'top' of such trees who have benefitted enormously, either strategically, materially, or both.
I agree, it is a fascinating time. What is most alarming to me is that I can never remember a moment in my lifetime where it's next steps and actions belonged in the hands of so few people. I have acquiesced to the fact that I have no control over what is coming...
