Actually, I think issuing a planned "leak" is quite a diplomatic way of saying "you're on our list--don't screw up" to a group of degenerate scummy "countries" who desparately need a saber in the face. Anyway, who on this list do you think is righteous enough actually to be offended?
More to the point, they need to be reminded that fat Willy isn't their "friend in the White House" any more.
If this is diplomacy, I'd sure hate to see a real threat. So the US now defines righteousness and righteously threatens other countries with WMD? I see a paradox here.
