That's not what happened,
The US sent Pakistan materials to supply to local Mujihideen to provide support to the US assisting the Northern Alliance, AKA the guys they were later supporting against the Taliban once the Taliban basically all but chartered the planes for Bin Laden.
You'd be amazed how many of america's problems in the region trace in some way back to "Pakistan did it."
Like it's not unreasonable to guess that Kissinger croaked because his old heart couldn't take how America's foreign policy was becoming way more aligned with those "commies" in India after just a few terrorisms and genicides on Pakistan's part.
