Far be it for me to sound like I'm defending the utter incompetence of #JoeTheFraud, but I'm not sure anybody could have executed any kind of withdrawal plan and not come out covered in shit.
Conceding defeat in any endeavor (and that's what it is when we just pull up stakes and leave) has political ramifications and it certainly affords the reigning regime - whether that's Trump or Biden or anyone - the opportunity to be smeared in feces.
I believe the central objection to this whole shitstorm isn't just "pulling out." It's HOW it was done. Plans put in place by Trump were cast aside; the intelligence community's reports to #JoeTheFraud were ignored. Definitive dates - 11 Sep 21 - were announced. Little to no effort was made to recover expensive equipment (I find it astounding that so much was just "given" to the Afghani Army) and God only knows what kinds of classified information were just left and forgotten about.
What I mean is that a stable, basically honest government where corruption of public officials is seen by the governed to be stamped out vigoroisly would have been a prerequisite for this to have any kind of happy ending. And lo; what sort of Afghanis were the sort of people to be "Public Enemy No.1" to the Soviets, the Taliwhackers, the Opium cartels and just about any other faction in the region looking to enrich themselves? Exactly the sort of people with sufficient personal integrity to make that kind of good government stick. Our own 20 year occupation hasn't really done the region any favors in that regard either (that I'm aware of; if y'all are aware of efforts that I'm not, then PLEASE educate me).
This entire effort was predicated and driven by nation-building. Again. Fostered and driven initially by GWB, it was an effort that was doomed to fail from the start. If an entire nation/regime is going to foster terrorism, turning it from an 11th century shithole into something approximating what we have isn't going to work in the long run. Lessons learned from Vietnam were completely forgotten.
That being the political calculus which obtains, it was almost inevitable that whenever we pulled out of Afghanistan, however we did it, this was going to be the outcome. The damn of it all is that the options available due to the Clinton Regime's corrupt mismanagement of the region and the Sept.11th attacks didn't allow for many alternatives to choose from at the time.
GWB just had to show the world he had a bigger dick. And for a while, he did have a bigger dick. But then, not having an extrication plan that didn't involve spending huge amounts of US taxpayer cash (and enriching lots of contractors), here we are 20 years later.
It's been argued that loss of life in the past 2-3 years in A-stan has been completely dwarfed by the murders in Shitcago. That may be true. And that a small military presence of 2-3K in A-stan would have been no worse than what we currently have in Germany and other parts of the world. Also true. But a complete abdication, along with running away from our embassy is a completely different animal, and that is exactly what #GropeyJoe decided to do.
