It's not Abu Dis or the Arab neighbourhoods of Jerusalem that Palestinians want. They want ALL East Jerusalem. A freeze or not a freeze doesn't change that.

The Palestinians use diplomacy,war and terrorism to try and change Israel's positions on the core issues while refusing to change themselves.
