These suggestions from Dennis Ross seem mostly on-point and it's nice to see someone with impeccable Serious credentials so totally uninvested in the idea that perpetual occupation is vital to securing American interests. Ezra notes yesterday that Sandy Berger has pretty sound views as well. I think substantial swathes of the Democratic advisor class have evolved their thinking (in a good way) beyond the point where the presidential campaigns are willing to go. That said, the persistence of magical thinking like "basically lock everyone in a room together until they come to an agreement" (from the Ross article) is pretty strange.
