The settlement freeze does more to stop peace talks than helps and it could cause a slow down in foreign Jews moving to settlements. The Roadmap calls for a full freeze and a stop to terrorist attacks. If the US allow for facts on the ground to stand then they are preconditions to negotiations and much like the Sweden/EU declaration on E. Jerusalem. Any negotiations between Israel and PA is doomed without some framework that brings them close to a deal with some pressure to make it happen, otherwise they will still be going when the next war starts. If US fails to force Israel to honor Roadmap fully then bothside should start rearming for the next war, which is looking more likely now.
