Take a 100kt nuclear weapon, drill down, 1000 feet (and limestone is perfect shock conduit), and then detonate. No more tunnels. No radiation unless you dig a well down to the glass chamber.
Very important primer. Interestingly that when the obama-biden admin forced the Israelis to stop the embargo of Gaza in 2012 and forced the re-entry of cement trucks that were supposed to be used for rebuilding of infrastructure, but sadly were used to rebuild their tunnels for economic reasons (ostensibly), but were also used for attack tunnels. They funnel about $700 million per year of goods as well as for moving military equipment and terrorists. Now biden’s clown government wants to lift the sanctions again, force a ‘cease fire’, and resume the building of tunnels. I pray that the Israelis tell obiden ‘hell no’. They must destroy Hamas in such a way that they can never return to power.
Nazis did the same with building tunnels.
Another similarity.
Pump seawater into the tunnels, then dry it out with CS gas.
