A nuclear one will go close to that depth, but no way a non nuclear one will go even close to that depth:

Using the 1.2 megaton B83 warhead—the highest yield weapon in the U.S. nuclear stockpile—could crush underground bunkers to a depth of about 1000 feet.

The IDF is doing fine. It is clear Ham Ass has more money and technology than expected and this is the new challenge.....stopping the money (hard) and materials (easier).

They are going to have to level Gaza. Internationally, they have to stop caring about the civilians.....there are none.

The US didn’t when we dropped the bomb and Israel should take the same attitude now. There will be civilian sacrifices which are tragic, but necessary to lower the overall death toll over time.

Don't need a nuke that big. Operation Plowshare showed that a 100kt nuke in a 1000m deep bore hole will obliterate tunnels for miles and create a nice swimming pool for Gaza. I say nuke the tunnels or flood them.

Peaceful nuclear explosions/nuclear engineering can solve this problem with minimal casualties:

The depth was misreported in the false story - it was 130 meters, not 400.
