I remember reading this somewhere years ago. The idea is that Israel will nuke Paris, Berlin, London, etc, in the event that the west cuts off their support and allows it to be defeated by an enemy force.
Is this just a dumbass conspiracy theory, or is there something to it?
The difference between MAD and the Samson option, is that in the former you're only attacking whoever attacked you, while in the former you're attacking bystanders that refused to intervene on your behalf.
