In May 2011, a poll of 500 Israelis, commissioned by the Jerusalem Center for Public Affairs, found that 77% opposed going back to pre-'67 lines; that 85% and 75%, respectively, supported keeping all of Jerusalem under Israeli control within the framework of any peace agreement and opposed transferring the Temple Mount to Palestinian control, even if the Western Wall were to remain in Israeli hands; that 84% believed Israel must maintain control of the Jordan Valley, even in the framework of a final peace agreement; that 60% believed that defensible borders would ensure security more than a peace agreement would; and 82% considered security concerns more important than a peace deal.[111]
