Bin Floggin and his buddies in sand-land have been threatening "jihad" against just about every country on the planet. Aside from a grenade launcher, he's seriously ill-equipped to carry this out.
If the United States wanted to declare a "jihad" on Afghanistan, all it takes is a few phone calls and some Air Force Majors turning keys to light up some serious stuff, and the candle will burn very bright.
If a nuke is used on US soil, there will be serious hell to pay.
