Then you understand how difficult it is to us seismic to identify deep voids. The energy will refract around the void. The tunnels are more than 50 m deep.

Our family invented the first real time seismic data processing for oil exploration.

What war? I didn't see a war. I saw a well-armed military obliterate an occupied territory and kill hundreds of civilians. Hamas was there before; Hamas is there now.

A two-state solution is not feasible given all the Israeli settlements in the West Bank.

Not feasible now. When will it be feasible?
Eventually the day will come when America no longer is in a position to protect Israel or send them money.
Gaza or its people will not disappear. Problems are just going to increase, now is the time for peace. Forget stupid things like military objectives. Find a solution
2 state or 1 state. Not eternal blockade

It couldn't have taken them all that long. Israel was last in Gaza November 2012.

There are reasonably fast ways to build tunnels: Tunnel boring machines, drill and blast, etc....but Israel would be able to detect the activity. And I would be shocked if a TBM is allowed in Gaza. If they are building by hand, using manual labor, it is a slow process. probably on the order of a few meters per day.

Then what, the Israelis missed them all last time?

Part that is missing is hand building is hard to detect....need to have a sensor within a few hundred meters.

The entire length of Gaza is only 25 miles, which they heavily patrol.

Clearly, you do not understand the difficulty of finding and locating tunnels.

It's not that hard to map 25 miles with MASW and ERT over the course of an entire year. The idea that Israel was surprised by these tunnels is preposterous. They have been sitting on the locations, waiting for a chance to exploit them. And that's why the tunnels didn't actually cause a huge problem.
