If Palestinians had been looking for a reason to join the protests sweeping the Arab world, Al-Jazeera provided one last week with a trove of leaked documents suggesting their leaders had made deep concessions to Israel in peace talks over the past decade. Among other things, negotiators apparently agreed to forgo the repatriation to Israel of most Palestinian refugees, a taboo issue if ever there was one. Yet across the West Bank, Palestinians remained mostly indifferent to the news. Few showed up at protests, and no mainstream figure called for President Mahmoud Abbas’s resignation. The backlash that some analysts had predicted never materialized.
