The eternal dilemma of Gideon Levy

Gideon Levy in his latest missive A society is judged by the way it treats its prisoners left his readers with a delicious ambiguity to resolve. The last paragraph of the article reads:

To many Israelis, that is not enough. They want more suffering and vengeance. The sight of the makloubeh the Palestinian prisoners cooked for themselves in their narrow cells infuriates them more than our appearance in the mirror. A society is judged by the way it treats its prisoners. And yet, if I believed that this collective punishment could bring relief to Gilad, maybe I would have joined them.

Who is it precisely Mr Levy wants to join? If it's Israelis, he seems to be late. If it's the prisoners, how could it be arranged quickly?
