> Leaving Afghanistan (to fail) has been a long time coming. Obama wanted to do it, Trump wanted to do it, Biden decided to pull/had to pull/tripped over the cord.
I don't think blaming the failure on Obama, Trump, or Biden is fair. Even blaming the failure on the way Bush handled the invasion after it began is unfair, since I think it was doomed to fail from the very moment of conception. I don't think it ever stood a chance of working in the first place.
Anyway, if you'd like to know more, there are interesting parallels between the Taliban's resurgence in the past few days, and the rise of the Saqqawists during the Afghan Civil War in the 1920s. Amanullah Khan's government and armed forces were struggling against a rebellion of tribal forces (the Shinwari) who opposed Amanullah's attempts at reform, particularly wrt the status of women. When Amanullah's forces were preoccupied with fighting the Shinwari, the Saqqawists used that opportunity to attack Kabul, which Amanullah's forces surrendered to the Saqqawists with almost no fight (sound familiar?)
The retreat itself was a massive failure, and that's to (at least partially) blame on the current leadership.
The Military wanted us to believe that "just a few more years" would prop up the regime, so they cannot come clean saying we cannot pull out without a proper evacuation because that would undermine the "just a few more years" argument.
Yes, that's the problem.
> The retreat itself was a massive failure
The retreat was a massive failure as a direct consequence of the occupation being so massive of a failure that the previous administration freed a Taliban leader for the express purpose of signing a surrender to the Taliban, and that the Afghan government and Army, unlike their South Vietnamese equivalents that stood and fought for years after the general US withdrawal and even as the PAVN fought into Saigon, collapsed swiftly, with the President fleeing the country and the army offering no resistance to the Taliban.
The idea that you can separate them is nonsense propagated by people still in denial about the totality of the failure of the occupation.
