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?
this isn't the same thing as the Samson option, which refers to Israel's willingness to retaliate against an enemy nation which has attacked it. OP's scenario is a complete fantasy that he picked up from someone whose brain was about a liter too small for their skull.
