Wait, what? There are also a number of countries that operate nuclear plants purely for civilian electricity production. Military applications are not the primary motivator.
Instead, civilian energy demands and energy independence are the motivating factors. Look at how Ontario leveraged its electricity supply in the early days of the trade war.
I said build not operate. The world situation has changed, 50 years ago nuclear power was a good idea to build. If you have a working nuclear power plant I'd generally keep operating it, and do small upgrades over time. However building a new one is something you should only do if you have military needs. (note that showing off is sometimes a military need)
