Abbas and the PA said at the beginning of the settlement freeze that they weren't going to pursue talks until Israel halted ALL building in the West Bank, including East Jerusalem. They never stopped building in East Jerusalem even during the talks. Only after US pressure did the Palestinians agree to talks in the first place. Also, stop saying that this wasn't a condition before because that doesn't even matter. The Israelis have continued building during peace talks for the last few decades. 10+ months isn't going to kill them for a genuine shot at peace.
