In Ukraine alone, there have been two major instances of military destruction of hydroelectric dams (Dnieper Hydroelectric Station during WWII and Kakhovka Dam during the current war) with the number of casualties far greater than that of all nuclear power incidents in history combined. Somehow, nobody's using that as an argument against hydro power.

If anything, Germany's reliance on Russian gas did a lot more to put the country in danger of war.
