As much as it pains to know that Shalit is not free, his freedom cannot be secured at an impossibly high price. The currency here from Israel's point of view should not in dollars, nor in the head count of prisoners to be exchanged, but more pertinently in the estimation if such a deal will bring more or less death and kidnappings to Israelis in the future. This is to my opinion the morally correct position that Israel should keep in mind when negotiating Shalit's release. This is a position ignored by much of the press.
