Goldblog seconds the Dish on substance:
I didn't think it was necessary for Bibi to do this, for any number of reasons: a) These are holy sites to Jews regardless of politics; b) I'm often a fan of the unspoken status quo, which is to say, Jews now have free access to these holy sites (something they didn't have when Jordan occupied the West Bank), so why mess with something that works? I'm all for negotiations about the permanent disposition of these sites, but this move seemed over-assertive and needless.
But really the main problem is UNESCO. This is nuance, I guess.
