The False Dilemma Fallacy

A well known, and often committed, logical fallacy is the false dilemma.[1] When you consider two variables (US Government, Al Qaeda), you have the following, logically possible options:

  US Government Al Qaeda
Involvement in 9/11    
x x

That's four possibilities, not "either the US did it, or Al Qaeda did it". As you'll note, "neither" and "both" are also options.

What happens when we add Israel, Saudi Arabia and Pakistan?
