I think realistically this is the only way in the turbulent times we live in. Even in the small and interconnected Europe, you have to be completely self sustainable when the need arises. We've seen more than enough broken pipes, power lines and the like in the last year alone to underline this need.
The last few days have also laid bare that there is no sovereignty without nuclear weapons. A civil nuclear fleet is a stepping stone to nuclear weapons stewardship.
(Even absent nuclear weapons, see the special treatment of Zaporizhzhia [1] over Ukraine’s other power infrastructure.)
