Don't forget that these are hardly ground breaking facts, al. I learned about the mujahideen in high school when I took modern history, then more about cold war period middle eastern affairs during a brief stint at TAFE post school.
Every single one of these groups, IS, Al Queda etc were supported, trained and armed in the late 70s/early 80s after the Soviet Union invaded Afghanistan. The groups of insurgents that came Afghanistan, Iran, Saudi Arabia, Iraq and Syria formed a loose alliance called the mujahideen and the US helped them. There were two major groups, Tehran Eight and Peshawar Seven. Peshawar seven trained in Pakistan and I think Tehran Eight in Iran, both trained and armed by the west and funded by the west. This is fact. It's the same as what we are doing with the Kurds now.
