There never were none. Some say that 9/11 was caused by the American government, so US troops could go into Afghanistan and destroy the heroin and stop it going onto the streets of the free world. They went into Iraq to oust Saddam and control the oil production. In both countries, they reinstalled new governments. Two that they could control.
Aliens are behind 9/11. It was the first step in their invasion to Earth.
Stop heroin from getting into the free world? Are you fucking kidding me? The aliens use heroin to gas up their UFOs.
