No doubt Shalit's case is tragic, but so is the fate of Palestinian prisoners in administrative detention in Israel. Shalit was a soldier in a combatunit. He probably knew about the risks. I think neither Hamas nor Israel are serious about the negotiations so I fear Shalit may meet Ron Arad's fate.
