Who are you going to isolate?



Establishing a cordon sanitaire sounds nice but in reality it won't work. You can isolate a country's government but not a faction that are participants in a terrorist campaign.

The very places you want to isolate have their peoples living in fear of these Jihadists. So you say leave them to their own means and condemn them to subjugation or death.

This is the problem with interventionist and isolationist theory. Either way you get condemned.
