Get the Israelis to map these tunnels and call in several Arc Light strikes.
Then go in and mop up the dazed survivors.
I apologize for my abysmal ignorance. What is an Arc Light?
The only such I have heard of is a fictitious cannon on Terran tanks in the computer game
Starcraft.
Cheers!
"Then go in and mop up the dazed survivors."
Not at 120 feet underground. Depending on the soil composition the tunnel occupants would barely feel a thump.
The Israeli's would need a ground penetrator. "Bunker Busters" can penetrate 20-40 (max)ft of concrete or from altitude 100 of just soil and light rock.
They would probably need two or three to get a concrete bunker of say 10ft concrete under 100+ft of soil and rock. Even then they would need them to stike the relatively exact same spot.
Now if they could get one to come in from space at 10000+ fps they might have better luck. Tough to aim though. We were looking at designing one around the time of the start of GWII. (
