Anyone a bit better informed would be skeptical and the arguments are on the table for years now. The gas problem is about heating which nuclear energy could only supply indirectly with a low grade of efficiency. Germany, for example, only ever had 6% nuclear energy at its height. You can pretty clearly identify populists that now propose to change course. It would minimally easy the burden, perhaps, but there are more efficient alternatives.

"People will die" from this mistake is hysteria. Nobody informed about the energy problems will take that seriously. Gas is not electrical power to start with.
