Apparently, there is no way to avoid the creation of a commission of inquiry once Operation Protective Edge is over. The commission will have to discuss what Israeli cabinet ministers are describing as a “resounding security failure.” Why didn’t Israel mark the threat posed by the Hamas tunnels as a strategic threat, as is now so obvious? Why didn’t it devote thought, effort, budgets and attention to this threat, just as it did to the rocket threat, which received an appropriate response in the form of the Iron Dome air-defense system?

The commission of inquiry will have to investigate three distinct tiers of questioning: Did the security forces have intelligence about the tunnels? If so, was it relayed to the political leadership? And if it was relayed, why didn’t the political leadership act accordingly? It should be remembered that had Hamas not rejected the Egyptian cease-fire initiative, Israel would not have discovered the scope of this threat, and Hamas would have continued digging and expanding its tunnel network, right until the moment it was deployed.

One senior Cabinet member I spoke with this week described that possibility to me: “Imagine," he said, “that we are in the middle of a conflict with Hezbollah up north. Our top-notch infantry brigades are up there, in the north, when suddenly Hamas deploys its network of dozens of tunnels all at once. Some 2,000 Hamas commandos suddenly burst out of them and embark on a killing spree, slaughtering thousands of people in the cities and towns across Israel’s south, from Sderot through Ashkelon, Netivot and Ofakim, maybe even all the way to Beersheba. Who would stop them? The police? The air force? It would take weeks to clean up the mess, and at the end of the entire process, we would find death and destruction across southern Israel. I know,” the minister continued, “that it sounds like a figment of the imagination, but based on what we are discovering these days, the scenario is far more realistic than it is imaginary. In this region, the reality easily exceeds anything we can imagine.”

What originally led to Israel’s ground assault in Gaza was the tunnel near Kibbutz Sufa from which 13 Hamas commandos emerged. They were seen coming out of the tunnel by scouts in an Israel Defense Forces observation post. Video of the ensuing battle, which took place that same morning, aired on all of Israel’s TV networks. The commandos can be seen coming out of the tunnel dressed in IDF uniforms, with all of the standard equipment, with body armor, camouflaged helmets and toques (knit caps) and an enormous amount of weapons. They crawled across the ground together, performing together rolls and rescue maneuvers, until, apparently, they suddenly heard the motor of one of the IDF’s unmanned aircraft or the ignition of a tank that was turned on in the sector by accident, and they raced and pushed themselves back into the tunnel. An IDF aircraft fired a few rockets, but not all of the commandos were hit.
