Wars the US waged in Iraq, Afghanistan, Syria, Yemen, and Pakistan following September 11, 2001 caused at least 4.5 million deaths and displaced 38 to 60 million people, with 7.6 million children starving today, according to studies by Brown University.
did they already plan to use afghanistan to export muslim extremism into xinjiang when they planned the invasion, or did they come up with that idea later?
I think they already had been, Uigyurs were fighting in the Soviet-Afghan war on the side of the muhajadeen and then brought that violence home in the 90s
CIA was heavily involved in creating the Afghan war though, Afghanistan would look like Vietnam or Cuba today if not for that.
I remember reading something about this in the final 9/11 investigative report.
