Or: Shhhh! That's not the way we're telling this story.
Hat tip to Pajamahadin, it seems there may have been 'links' between Iraq and Al Qaida, possibly even fairly directly to 9/11, all along.
Theirs is more of a shot at the 9/11 Commission and its,,, umm,,, less than zealous follow-up of intelligence received; the Weekly Standard has some very interesting information, regarding events in Europe, well prior to the 9/11 attack.
[regarding two Iraqi intelligence agents captured in Heidelberg] German authorities, acting on CIA recommendations, had been focused on monitoring the activities of Islamic groups linked to bin Ladin. They discovered the two Iraqi agents by chance and uncovered what they considered to be serious indications of cooperation between Iraq and bin Ladin. The matter was considered so important that a special team of CIA and FBI agents was sent to Germany to interrogate the two Iraqi spies.
Conclusive? No, but most assuredly worthy of a lot more consideration than the 9/11 Commission gave the implicational possibilities.
