It is somewhat, well, idiotic to suggest that Israel's policies to the Occupied Gaza Strip is not working. For instance, what does "working" mean? Idyllic peace? That won't happen as long as racist-Palestinists get to foist the conceit that Arab Palestinians are the only Palestinians and that Jews, ie (along with Samaritans) the other Palestinians don't exist. "Working" in a practical sense must mean "the best that can be done". In that sense Isreali (Jewish Palestinian) policy is probably working. My guess is that "being nice" will end in more rockets, not fewer.
