Scoblete concedes that Larison makes a "very fair point with respect to Pakistan and their support for the Afghan Taliban" but he doesn't "think it applies to allegations that they sheltered bin Laden or other al-Qaeda members":
Keeping bin Laden secreted away doesn't advance Pakistan's aims vis-a-vis India or Afghanistan, as far as I can tell. And even if the ISI did have some kind of rationale, so what? Ultimately, we have to have some red lines and harboring fugitives responsible for slaughtering Americans on American soil is surely one of them.
