It totally makes sense, because nukes don't change the basic premise that leads to war. Unless you use some perverted version of "logic" that is, which says that when a madman has nukes then you must bend over and let them feck you every time they threaten to use them and turn a blind eye to anything they do. What kind of spinelessness is that?
There just comes a time when you say it's preferable to fight and die than live in a world shaped by such people.
Liberty or death is a foundational motto of many nations who had to fight a bloody rebellion with huge human toll for their freedom and independence. Why would I want to live in a Europe ruled by Nazis? How is that preferable?
So yes, even if Hitler had nukes you'd fight back. And if he used nukes, you'd use them back. And if that caused MAD then it's still better than a Nazi world. The survivors would rebuild.
