Ross tackles the question of double standards. Larison's post is pretty powerful, I'd say. His money quote:

The official opprobrium heaped on Palestinian militants, for example, is primarily a matter of condemning the enemies of an allied state; their use of terrorist tactics is secondary to whether or not they are labeled this.

Ross's quibble:

It's that "entirely" that I don't buy.

I must say that whatever reservations I had about the Walt-Mearsheimer book (and I largely share Ross's assessment), Walt's counter-factual post on Gaza has generated a lot of great blog debate. It has helped out the deeper debate we need to have. As has the entire Gaza bombardment.
