Let's talk about the nukes

[Myth]

If ISIS got momentum and significant territory I bet the option of small tactical nukes would be considered.

Isis won't last, they are doomed. They have no heavy armour, no SAM apart from shoulder mounted crap, absolutely no airforce, poor intelligence and in general they're your typical band of ragheads with AKs and yatagans.

France, the UK and the US can plop down a few carrier groups and sweep them off the map.

ISIS with modern tech AND training to use it would be dangerous. But who would give them tanks and SAMs?
