I still don’t know what is stopping Israel from installing the necessary infrastructure to intercept these tunnels. Soil carries sound so efficiently that with sensors planted 100 feet down the sound of digging should be easily detectable.
I don’t know. I would think the technology would be within Israel’s grasp. Maybe they didn’t entirely recognize the threat until learning of the Yom Kippur attack plans. The smuggling tunnels to Egypt, they haven’t really had access since leaving Gaza. Should have kept the Philadelphi corridor, should now.
