Give me a a break. 99% of all terrorosts attacks don't involve VX gas or atomic bombs but instead much more prosaic materials like chemical fertilizer, LPG bottles and nails and nuts, and most take the form of bomb cars/boats, suicide people (yup,even girls, preferably pregnant, cause they can choose if to die in the hands of her own brothers or die in the name of some "struggle") and their targets are buses, shopping centers and discos.
That guide to survive a biological, atomic & chemical attack is cool, no doubt, but look at real world stuff.
