Can someone defeat a nuclear power?

Hungarian Prime Minister Viktor Orban believes that only in a fairy tale there could be a situation in which Russia would be defeated and it would come to terms with it.

"I don't have the fantasy to imagine that anyone can defeat a nuclear power. To think that the Russians will sit idly by and watch them being defeated, their political system being broken, their president being assassinated, a drone attack over Red Square, to believe that they will silently watch and resign themselves to military defeat, is only for those who have not grown out of childhood. That's what happens in a fairy tale, but not in reality," Orban told Kossuth Radio.
