I was thinking about how the war on terror started with 19 men armed with nothing more than boxcutters hijacking airliners and slamming them into buildings and metamorphosed into a crusade for the destruction of WMD capabilities in the hands of terrorists and their sponsors. I had already typed these words on the screen:

"It has been more than three years since 9/11 and there is no evidence that anybody has attempted a WMD-based terror attack in this time period".

completely forgetting the anthrax attacks that immediately followed 9/11. This lapse of memory has convinced me that the anthrax attacks were staged precisely to link terrorism with WMD. The way the investigation has been conducted (click here for a good overview of this) has also reinforced my belief. It is almost a certainty that world events would have followed a different course had either 9/11 or the anthrax attacks happened in isolation (i.e. not both of them together).
