As an ageing "Boomer" I grew up with the ever present threat of nuclear war..Cuban missile crisis and all. Used to get pretty depressed about it all. Like many of us, I found the best way to deal with it was to forget about it and live for the moment (did that particularly well in the sixties). With all the other threats that the planet faces, the nuclear issue has sort of faded into the background.
With the original nuclear club members it was more likely that a nuclear exchange would happen by accident than by a suicidal first strike (MAD)
I suppose Iran, North Korea, Scotland and Tasmania have equal rights to join the club but I think it would make the world an even more dangerous place.
I'm with Raedwulf here. Solar and other renewables are better value.
Nuclear power is mainly a spin off from the weapons program. If you really do the math(s) and include an allowance for the still unsolved problem of waste disposal then it makes no sense.
