In December, an American court entered a default judgment against Iran for allegedly having a hand in the September 11th attacks. 1
On the other hand, a 9/11 Commissioner and the Co-Chair of Congressional Inquiry into 9/11 both say in sworn declarations that the Saudi government is linked to the 9/11 attacks. 2
Then again, right after 9/11, Bush, Cheney and Rumsfeld accused Iraq of having a hand in the attacks.
People may not remember now, but – at the time – the supposed Saddam-9/11 link was at least as important a justification for the Iraq war as the alleged weapons of mass destruction. 3
Of course, the Afghanistan war was largely based upon the allegation that the leaders of that country – the Taliban – had harbored Bin Laden and other Al Qaeda terrorists. In other words, the U.S. government treated Afghanistan as being complicit in 9/11 by giving refuge to the 9/11 attackers. 4
At a minimum, America unintentionally created an atmosphere in which Al Qaeda terrorists could thrive. But numerous former U.S. military and intelligence officers think that rogue elements within the U.S. government intentionally allowed or facilitated the attacks.
