“Egypt flooded thirty-seven cross-border tunnels in southern Gaza back in 2015”
I was not aware of this. So, just eight years ago Egypt did this to stop smuggling back and forth into and out of their country.
So a predominantly Arab country did this to the Palestinians?
How is it that I have never heard about this until now?
Flood the tunnels, use drones to place underwater explosives. Upon detonation the over pressure wave would cause numerous cave ins and damage to any remaining infrastructure.
