Query: Scary to say the least

As a molecular biologist, I was shocked at what was discussed in this book. Descriptions of potential weapons, or weapons that were being worked on when the Soviet Union fell sent shivers down my spine. The authors have thouroughly researched the material and present it more as fact rather than a story.To learn that West Nile virus was used as a "model" to demonstrate how the government could "contain" an invectious disease, only to find that we totally failed to contain demonstrates how real this danger may be. Unfortunetly, you also gain the insight of how politics actually works. The creation of the programs would cost billions and if they "work" they appear as wasted money since the programs success would result in no attacks.Some parts of the book read rather slowly, but serve as the foundation required for the modern discussions that are addressed later in the book.
