Here are the definitions you choose to attribute to "positions" of NPR/PBS (neither organization was involved in the survey, btw - see the page immediately preceding the report proper)...

I am aware that neither organization was involved in this report. I am objecting to using positions touted by these organizations as the standards of truth or misperception. In other words, I am complaining that the NPR/PBS positions are defined as true by the authors, and that other positions are "misperceptions." The minimal data they give to back up their positions doesn't stand up by itself.

For example, they are wrong that there have been no links at all between Iraq and al Qaeda.

The linkage between Iraq and terror groups is based on a wide foundation of sources, some credible, some less so, some circumstantial. To hear the authors talk, you'd think the whole concept was based on that one single meeting in Czechoslovakia (which Czech intelligence still stands behind.) This is similar to the recent attempt by antiwar factions to balance the entire rationale for invading Iraq on the uranium/Niger connection, and then negating it based on a few forged documents and Wilson's report. Ignored was the fact that intelligence sources had other links between Iraq and African uranium (from other nations besides Niger) and that British intelligence had other sources on the Niger connection besides the forged documents.

Just a few articles discussing links between Al Qaeda and Iraq:

Weekly Standard

Some media opinons in 1999, when Clinton's foreign policy made it fashionable to link Iraq and terrorism.

However, a striking misperception occurred after the war, when the US failed to find any weapons of mass destruction or even any solid evidence of a WMD program.

This is blatantly false. After Kay's report, anyone claiming there is no evidence of WMD programs in Iraq is not playing with a full deck.

Get it straight: a lot of what they are calling misperceptions, and egregious ones at that, are not proven to be such by any means. Given that, the rest of the report falls flat.
