Random midnight thoughts:
UN, NATO, and WHO would all be on the same page if they were at a wedding and someone was wearing white out of malice: Spill as much red wine as physically possible on them.
UN: would ask bride first, and then attempt to carry way to many glasses of wine with him so he could "accidentally" drop all of them on the person, act all innocent and apologetic and then start crying if they start yelling at him (NATO and WHO would then come in to defend him and say he's drunk or smth)
NATO: he'd be nonchalant about it, but he would just keep throwing wine at the person until they're forced to leave cause no one wants someone like that at a wedding
WHO: straight up just throw wine at them, no hiding it, and then chastise them for wearing white until they cry or leave
