A flurry of gestures toward the Palestinian leadership suggests that Israeli Prime Minister Benjamin Netanyahu, in his new role as leader of a center-right government, is warming toward the resumption of peace talks — or at least giving the appearance of warming; call it a rosy glow rising from a pair of announcements on Monday. One was about Palestinian prisoners who had been carrying out a mass hunger strike for weeks inside Israeli prisons. With several prisoners near death, Netanyahu approved an agreement that improves prison conditions and permits visits by family members in the Gaza Strip, the heavily guarded enclave that Palestinians have been allowed out of only for medical emergencies. Greeted by Palestinians as a victory, the deal eased concerns that a prisoner’s death might combust what are usually routine protests planned for Tuesday’s commemoration of Nakba Day, the “catastrophe” of Israel’s 1948 victory over Arab forces trying to prevent the establishment of a Jewish state.
