A new alphabet soup of agencies have sprung up, including the Bureau of Domestic Intelligence and the mysterious BuDark. It is a time when news of the capture of the 2001 Amerithrax perpetrator is overshadowed the next day by a NUCDET in the Iranian Tactical Area of Responsibility:
In post 10-4 America homegrown bio-hackers create real viruses, not computer ones, while Sunni factions in Iraq test the results on captured Jews and Shiites. Genes are spliced into yeast to create airborne mad cow disease, and dispersed by ordinary fireworks from the back of a truck.

Israel starts assassinating the extended families of suicide bombers, but still they come.
While the House of Saud is overthrown by a US backed coalition of Arabs in a "controlled burn" revolution, hoping to keep the oil flowing, liberals in Congress, backed by Madam President and incensed by the discovery of "patriot files" on them systematically dismantle the FBI even as the final class of agents undergo training at the FBI Academy on the Quantico Marine Corps Base in Virginia.
