I agree. With most of your scenario--the muzzies are not innovators, for the most part they go with what works.
Car bombs and bomb belts will be the delivery mechanism, but they need maximum shock value--that doesnt come from DC or LA, that comes in the heartland. Imagine your scenario (GOD FORBID) at the Mall of Am in MN. Day after Thanksgiving.
Only one problem, there'd be no living muslims left in this nation that night, because the retribution would be a bi*ch..Bush's peaceful religion hijacked rhetoric would not keep the masses at bay...
Yes, that would be horrific, but the Mall of America is only one location. The scenario that I have imagined involves hundreds of Wal-Marts across the nation. Imagine, if you will, hundreds of suicide bombers doing their thing at the same time. Let's say 4 PM eastern time on Saturday, 3 PM central, 2 PM mountain and 1 PM pacific.
The only problem that I see here is finding several hundred terrorists willing to blow themselves up. That seems to not be a problem these days.
