I'm not an expert not pretend to be one. IMHO your "They are extremely tough targets, and fairly easy to defend" is quite different from what I quoted.

Maybe. Maybe not. Nobody knows for sure, however after each of these click/bang the "there will be no more problem!" thesis seems less and less prominently published.

I doubt so: 416 industrial nuclear reactors are deployed in the world today. They produce 10% of the electricity, itself 20% of the final energy, so nuclear power produces at best 2% of the energy consumed. Nuclear power would provide 10%
