If I were you I would be afraid to be very successful in your drone aggression against Nuclear Power
Nah. Russia has lots of nukes, but Putin knows damn well that if he tries to use them, there's a good chance they won't work, and if they do work, he, his family, his friends (if he has any), and the rest of the inhabitants of the Kremlin and the inner suburbs of Moscow, will be a trace contaminant in a pool of radioactive glass within the hour.
He's not going to use them just because his army gets pushed out of the occupied parts of Ukraine.
And everyone's getting bored of the empty threat that gets trotted out at every reverse. If you are losing, nukes will just make you much bigger losers (and historical and international pariahs on a level currently only enjoyed by the Third Reich).
