Pakistan had little to do with Taliban victory, US barbaric invasion, greed and incompetence did, and the exit on the cheap after destroying everything. Where is your critique of the US? The US trained military fell in quickly as expected because it was a colonial implant. This current skirmish is the fault of Pakistan violating international law by bombing Kabul and the Kabul government responding to it to save face, just as Pakistan would have done in case of attack. The Taliban were a positive development for Afghanistan post "Mujahideen" barbarism of US/ISI.
