Today he has posted on Israel, or actually, on the hope the Obama administration will put lots of pressure on, and distance itself from, Israel. Personally, I think if Israel ends up with a coalition dominated by our far right, Netanyahu will deserve a modicum of pressure, and for that matter, so will we, so as to force us to decide if settlements are important enough to face down our American friends over. But there are various "ifs" in that scenario. And either way, it has little to do with peace, since our war with the Palestinians isn't about settlements, of which there are none in Gaza.
In the meantime, Greenwald's main thesis, it seems to me, is that the Obamaites must put lots of pressure on Israel; the Palestinians, if I read correctly, don't even get mentioned. The implication being that the lack of peace is mostly the fault of Israel, and marginally the fault of the Bush administration for allowing this.
it's hard to believe that George Mitchell was willing to take on this assignment unless he has the authority to apply the pressure on Israel which is an absolute pre-requisite for any hope of success. For now, those who desire a serious change in U.S. policy towards Israel should welcome any signs -- even limited and preliminary ones -- that the U.S. is willing to forcefully and, when necessary, publicly oppose and condemn Israeli actions (as we do with all other foreign countries).
