Have the north Koreans and Iranian's been invited? If not, then the whole thing is superfluous, and a total waste of time money and energy, however, the after dinner piss up is worth the effort, as is the 5* hotel accommodation, for the delegates, along with their " Secretary's".................... Cynical, me, no, perish the thought, as if, never!
Oh, goody, another talking shop that will achieve the square root of sweet FA but lots of *important* people will get to fly in on private / chartered jets, stay in an expensive hotel and get driven round in chauffeur cars.
Meanwhile the usual suspects (NK, Iran, China) will continue to do as they please.
