I thought this article was pretty helpful in setting the game board. It's interesting, and unfortunate, that Hamas seems to have come out of the Gaza invasion more popular than before, at least in the West Bank. It's especially interesting and unfortunate that such an advance for Hamas is coupled with the likely victory of Benyamin Netanyahu and the bloody-minded Likud party next month. In fact, polls show both Likud and the far-right Yisrael Beiteinu party making huge gains.
The cause of peace has apparently been outflanked after eight years of Republican negligence. I have a bad feeling that Gaza was just the prelude, and I doubt anyone can stop what's coming now.
