That's what we do. We pick a group in a middle eastern country, and we fund, train and equip that group, because we believe they would best support our interests in the region. While doing this we're aggrevating the other groups because we're helping their enemies.
We've done this over and over and over and over again, and have even changed sides over the course of time. We're the ultimate meddlers. Not condoning any of their actions, but I would be pretty upset too if foreign entities were consistently fiddling with our politics, invading, and dropping bombs.
