From a humanitarian standpoint I can see the Palestinian focus on the release of prisoners, but I don't see how this advances the ultimate goal of the creation of a independent, sovereign Palestinian state. Israel will use any action by the PA as an excuse not to move forward and the Palestinians will seek international support anywhere they can find it. Since the Israelis will add condition after condition ("Jewish state", military presence in Palestinian state, etc.) to insure a failure of the negotiations, the Palestinians have few peaceful options, but as settlement building continues and armed resistance remains abated, as it has for nearly 8 years, it's clear where the obstacle to an agreement lays; it lays with the Israelis. With attacks on their population reduced to nearly none, what is their motivation to move to an agreement? Boycott, divest? Doesn't seem powerful enough.
