In short, this article makes a strong case that our Russian "allies" (who were opposed to us going to Iraq) swooped in before US forces ever arrived and transported the explosives to Syria while on a mission to dispose of any evidence linking them to Iraq's rapidly growing arsenal.
Read the story for more details. If it turns out to be true, there could be all kinds of serious consequences both for the upcoming election and for international relations. If this is true, it will be interesting to see Kerry try to wriggle out of his past stance that we should have solicited and pandered for Russia's support. If it is correct, it also kills the idea that terrorists stole the weapons out from under our incompetent noses because this took place before we arrived at the site.
Something else to think about:
If this sort of thing was going on and our various allies were making weapons and paperwork disappear, perhaps there were some WMD's that suffered a similar fate. It would be interesting to find out if Russia, France and/or others who were milking the "oil for food" program, selling weapons and taking kickbacks had something do with the absence of WMDs. While WMD's were never the heart of the Iraq issue for me, they have been at the forefront of US politics and articles like this make you wonder just how much our UN "allies" may have been contributing to the problem.
