Chait sees Romney's comments on Israel and Palestine as a pander to conservative "Jewish donors have very right-wing views on Middle East policy":
Romney is aware of the dangers of moving toward a two-state solution, which are real enough, but he seems blithe about the dangers of the status quo. It’s certainly true that lots of Palestinians want to destroy Israel (though it’s not true that “the Palestinians” as a whole want this, as Romney’s formulation implies), and this complicates the prospects for a negotiated settlement.
But there’s not a whole lot of evidence that continuing the occupation is making them hate Israel any less. And if you lack any plausible mechanism for delay to improve conditions, then a short-term focus on immediate security becomes, by default, a long-term plan for a one-state solution. That is the Netanyahu “strategy,” and Romney appears comfortable identifying himself with it.
