Underground Empires: Hamas v. Israel

Senior members of Hamas’s leadership in exile met in Doha, Qatar, earlier in February 2024 amid concerns that its fighters were getting mauled by an Israeli offensive in the Gaza Strip. Enemy troops were killing dozens of militants each day as they methodically overran Hamas strongholds. Then a courier arrived with a message from Yahya Sinwar, the head of Hamas in Gaza, saying, in effect: Don’t worry, we have the Israelis right where we want them.  Hamas’s fighters, the Al-Qassam Brigades, were doing fine, the upbeat message said. The militants were ready for Israel’s expected assault on Rafah, a city on Gaza’s southern edge. High civilian casualties would add to the worldwide pressure on Israel to stop the war, Sinwar’s message said, according to people informed about the meeting… 

Hamas fighters are now trying to avoid large firefights and instead use small-scale ambushes—using tools ranging from rocket-propelled grenades to recorded voices of hostages to lure Israeli troops into traps.  The ambushes have little chance of holding territory against Israel’s armored maneuvers. But they’re tailored to Hamas’s limited capabilities…Many in Israel’s military, from senior commanders to ordinary soldiers who spoke to The Wall Street Journal, worry that their accumulation of tactical wins on the battlefield might not add up to a lasting strategic victory. After nearly five months of intense fighting, Israel is still far from its declared war aim of eliminating Hamas as a significant military and political entity. “Fighting the enemy is like a game of whack-a-mole,” said an Israeli reservist in Khan Younis with the 98th Division….

Degrading Hamas’s capabilities is a realistic goal for Israel’s military, said Hussein Ibish, a scholar at the Arab Gulf States Institute, a think tank in Washington. But sustaining it would require fully occupying Gaza, which would give Hamas a target for a never-ending insurgency, he said. “Recent history shows that you can be an effective insurgency on a shoestring,” said Ibish. “Anyone can make an IED,” or homemade bomb, he said. “It’s easy to get a pistol. If you’re willing to die, you can kill soldiers.” 

Hamas… has shifted to hit-and-run attacks by tiny groups of two or three men, sometimes just one individual….Other Hamas ambushes use so-called sticky bombs, improvised explosives that attach themselves to Israeli armored vehicles with magnets or duct tape.…Hamas also tries to kill Israeli troops by putting booby traps in buildings throughout Gaza, many Israeli soldiers say. Booby traps have been widely found in the homes of Hamas operatives, but also in many civilians’ homes, Israeli soldiers said. Early on the explosives were placed around the buildings’ entrances. The Israelis soon stopped using the front door, instead blasting or bulldozing their way through the walls of a house. Hamas has adapted, placing explosive traps in items inside buildings, from gas storage balloons to children’s’ toys, Israeli soldiers said….In other cases, Hamas used voice recordings of hostages begging for help in Hebrew to try to draw soldiers into an ambush…

The Israelis have made only partial progress in finding and destroying Hamas’s vast tunnel network. Israeli officials now estimate that Hamas built around 350 miles of tunnels under Gaza, which is less than 30 miles long and up to 8 miles wide. There are thought to be several hundred tunnels under Khan Younis alone, which occupies an area roughly the size of the Bronx in New York…Hamas uses the tunnels as military headquarters, to maneuver across the enclave’s cities, protect its leaders, hide Israeli and other hostages, manufacture weapons and conduct hit-and-run attacks. The tunnels also contain a fixed-line phone system that Hamas used to communicate earlier in the war, along with walkie-talkies, burner SIMs and satellite phones. But with Israel hacking into those systems, the militants have increasingly shifted to using runners to convey verbal or written messages. 

The Israeli army has found no systematic solution for finding and destroying Hamas’s tunnels, many soldiers said. Tunnel entrances have been found in homes, schools, mosques, courtyards, streets and farm fields. Some are covered by steel doors, others by mattresses in a home. Israeli forces have mostly relied on drones and robots to search tunnels, only sending soldiers in later to avoid firefights in the narrow passages.

How to Detect Humans Under-the-Ground: Surveillance Best

Tunnel-digging in times of conflict has a long history. These days, secret tunnels are used to move weapons and people between Gaza and Egypt, and by Kurdish militia operating on the frontier between Syria and Turkey. But the same principle applies. What happens underground is hard for the enemy to observe. Digging for victory is therefore often a good idea…

That, though, may be about to change. Real-time Subsurface Event Assessment and Detection (RESEAD), a project being undertaken at Sandia National Laboratories in New Mexico, uses novel sensors to make accurate maps of what is happening underground. This will, no doubt, have many civilian applications. But Sandia is principally a weapons lab…The sensors themselves are a mixture of accelerometers, which pick up vibrations, current detectors, which measure the electrical-resistance of rocks and soil, and subsurface radar…

Exactly how RESEAD sensors would be put in place in a zone of active conflict remains to be seen. But the system could certainly be useful for other sorts of security. In particular, America has a problem with tunnels under its border with Mexico being used to smuggle drugs and migrants into the country. RESEAD would be able to detect existing tunnels and nip new ones in the bud.

Zero Radioactive Leakage: China Experiments with Nuclear Waste Disposal

China has chosen a site for an underground laboratory to research the disposal of highly radioactive waste, the country’s nuclear safety watchdog said in September 2019.
Officials said work would soon begin on building the Beishan Underground Research Laboratory 400 metres (1,312 feet) underground in the northwestern province of Gansu, in the middle of the Gobi desert.

Liu Hua, head of the National Nuclear Safety Administration, said work would be carried out to determine whether it was possible to build a repository for high-level nuclear waste deep underground….Once the laboratory is built, scientists and engineers will start experiments to confirm whether it will make a viable underground storage facility…

Lei Yian, an associate professor at Peking University’s school of physics, said there was no absolute guarantee that the repositories would be safe when they came into operation.
Leakage has happened in [repositories] in the US and the former Soviet Union … It’s a difficult problem worldwide,” he said. “If China can solve it, then it will have solved a global problem.”
China is also building more facilities to dispose of low and intermediate-level waste. Officials said new plants were being built in Zhejiang, Fujian and Shandong, three coastal provinces that lack disposal facilities.
