Oh really they have ZERO ability? Or do you have ZERO imagination? Which is it?
Lets play this scenario out using only 5 low yield weapons.
Scud launch off the coast of New York, air-burst EMP shuts down most of the East coast.
Next day nuke in St. Louis pops off...then an hour later one pops off in San Diego in the Harbor. About 12 hours later the Jihadist give us an ultimatum. Leave the ME, Europe and the Far East or we will continue popping off weapons.
Please explain the reaction of the US Populace to the uncertainty of a weapon being in their city. Then please explain the results of losing San Diego, St. Louis and most of the East Coasts electronics. Compare and contrast the ability of the Jihadists to absorb hits to our society.
Then explain what changes such an attack might bring about to our way of life.
And for giggles they throw some Anthrax around...I mean boy that sure would be a fun week in this country. We could shake that kind of week off in a couple of hours eh?
