Ring the middle east with a fence. Guard the fence. Kill anything coming near the fence on either side.
It’s that simple.
Something even simpler, and historically proven effective: colonialism.
Looking around, the muslims in America are practicing it on us, and the muslims in Europe are practicing it over there.
Alas, colonialism goes hand in hand with supremacy, whether racial or cultural, and we have moved beyond that. We have moved beyond killing or even standing our ground against colonists in our midst; which is why history will move beyond us.
