I don't have any problem with China developing nukes. I have a problem with us not developing nukes. I don't think they'll have fusion in our lifetime.
US has 150-200 yrs worth of coal. Coal is even convertible ["gasifiable"] into oil - at something like $30s a barrel. Thus we could afford to wait till the fusion energetics comes on line - which could probably take, say, 50-80 years at most. And if the Chinese want to build more Chernobyls - more power [double entendre] to them. Thus I also do not have any problem with China developing nuclear energetics.
