There were not 3000 fellow american killed in 9/11 I believe it was several hundred. The nation that suffered the most nationals killed in 9/11 I believe is Australia.
I believe it is for oil. US used Iraq to fight Iran, when Iraq decided not to dance to US tune anymore then the games started.
US does nothing about North Korea, those poor people are living through hell, in darkness and isolation.
US went into Iraq illegally, kills its citizens illegally, plans to steal its oil and cover up the real picture in warped media coverage.
Its all about oil.
