ISIS is like a pack of savages, capable of little more than cheap thuggery on a large scale. But they seem to have some long term dreams and goals involving nuclear annihilation:
This is no doubt just the insane dreaming of a bunch of rabid knuckleheads, but it is instructive as to the mindset. Where would ISIS actually get nukes, though? They won’t be stealing them from the Israelies, and the Iranians probably wouldn’t want them to have nukes. The Pakistanis, perhaps. Fortunately, the one source that ISIS *could* have tapped for nukes, the Iraqi nuclear weapons program, was finally and permanently dismantled in 2003.
Imagine a world where the ’03 invasion of Iraq didn’t happen (perhaps Gore won in 2000). So by 2005 or so, the inspection regime ends; the Iraqi nuke program recommences. By 2015 the Iraqis have themselves some nukes… as do the Iranians and the Saudis. Saddam kicks the bucket in 2016; Iraq falls into civil war, with the Saudis pushing in from one side, the Iranians from another, perhaps the Syrians from a third side. A pseudo-ISIS forms, this time armed with Iraqi nukes and Iraqi nerve gas and Iraqi bio weapons. Let the chaos begin!
