Remember the Afghan Mujahideen? We supported them so they could fight our enemy, the Red Menace of USSR. The Afghan Mujahideen turned into the Taliban, and we know what they did.

Guess who just signed a deal with the Iraqi People's Mujahideen, a Hussein-supported group that combats Iranian groups, a group that "supported the takeover of the American embassy in Tehran in 1979" and were labeled a terrorist organization by the US in 1997? Yeah, one guess. Sure, they're cooperating now....
