always possible. I would think more likely that the government would fall and be dumped on their royal bum sooner than later
but your use of the word revolution is interesting ---- it wouldn't be the first time that a country went off the rails - a country that people would have said 'who woulda thought'
god help us if NZ does get unstable - it's one of the few places where one can think of a cultured and safe bolthole in the south
personally I think they'd be too smart for anything approaching revolution - but, who knows == peace, democracy, freedom really do live on thin strings and if one is severed, often the whole thing begins to swing wildly
