I haven't seen any evidence that we are getting permission from the UN to bomb selected targets.........YET! This certainly effected our bombing success in NV.
Well I don't know about the UN, but I do recall in the "other war" that we had all sorts of different "fire zones" of which not many were "free fire zones". Many we had to have permission from regional civilian authorities (rife with cong influence), regional military authorities (man of whom were not to be trusted), and in other instances only a Bridage CO or higher could get and then give us permission to "rain death" on the little buggers. I could lauch into a war story here but will stiffle it.
Bottom line is that each day we are in Afganistan "cleaning up" I get the "mission creep" heebie jeebies.
