At least in my professional experience, this is without precedent. The closest parallel would be the 1976 Entebbe hijacking and hostage-taking by two Germans and two Palestinians on a flight from Tel Aviv to Paris. Hijackers held 103 Israeli hostages, once they released the 148 non-Israeli hostages. Hamas holds twice the number of hostages, and in very, very different circumstances. In Entebbe, the Israeli government knew where they were, they were in a single place – the airplane – which had been forced to land in Entebbe, Uganda, after taking off from Tel Aviv. And that’s where Israeli commandos were able to rescue the hostages. In Gaza, we don’t know where they are. We know for sure they’re scattered throughout the tunnels, likely in lots of different small groups. Hamas will presumably then use them as shields if fighting begins on the ground. They might think that that would encourage the Israelis not to make a major attack – to keep Hamas from killing all the hostages. We know that Israeli Prime Minister Benjamin Netanyahu isn’t keen on a major ground assault, and this really puts the onus on the Israelis for how the hostage situation ends.
