If we entirely abandoned the middle east, how many years do you think it would take before it became a problem we couldn’t ignore? The major countries (Iran, Turkey, Saudi Arabia) would quickly have nuclear bombs, ballistic missiles, and radical extremist islamic governments. Not sure that would go well long term.
So that means we go to war with all of them?
After years of detachment it would be easier to flex muscle and say go ahead we will nuke back starting with your magic rock shrine. Stay in your yard.
