Post 9-11, was our intelligence so bad that we invaded Iraq, or so good that we haven't been attacked since?

Or maybe, 9-11 was an inside job, we purposely lied about WMD's, and we haven't been attacked because there is major terrorist threat. Apparantely Al-Qaeda can't figure out how to cross the border like 100,000's of illegal do every year. The big bad Al-Qaeda, are you following for the NWO crap?
