Maximilian Forte at Zero Anthropology has the backstory and larger videos. Ironically, of course, the mujahideen used to be part of the CIA's community. Had this video been about mujahideen killing Soviet rather than US invaders of Afghanistan, no doubt it would have stayed up on YouTube.
We will beat you, CIA team... Inshallah we will beat you down. Don't think that you just pressing a button, killing mujahideen, you are safe. Inshallah, ... death will come to you ... in unexpected ways. [Inshallah] Look, this is for you: it's not watch... it's detonator, to kill as much as I can, Inshallah. [Inshallah] This is my goal: to kill you, to kill your partner, Jordanian partner, and Inshallah I go to the [Arabic] paradise and you will be sent to the hell. [Arabic] we will Inshallah see you again. [Arabic]
