Let's talk about the nukes

[Papewaio]

Stuck in a time warp?

No, I don't believe that any option is off the table if:
a) It's in the armory
b) There is a serious enough situation to warrant it
c) Drums of war prevail

So there are tactical nukes.
If ISIS next terrorist attack is an order of magnitude larger then 9/11 and they make significant headway towards a Caliphate or they are at Israel's doorstep.

Then we will see an escalation of weapons used.

If ISIS still maintains momentum then heavier and heavier weapons would be brought in until nukes are used. Only UN veto ISIS hasn't attacked is China. Do that and the entire security council will not veto an attack.

Likelyhood bugger all. Has the nuclear weapon age ended probably, but they said that about history too...
