Losers define winners and history. Winner (and loser) is a property of a relationship not a characteristic of a person. It takes two to tango, both matter.
What do you suppose history would be like if Hitler completed his objective? We'd be speaking german here in Norway for one, and I doubt that we'd be learning of the heroics of the allied forces during the war. We'd be learning about how the blessed third reich blossomed and a vision of the great fuhrer came to life. Churchill would be remembered as a warcriminal, and Himmler, Goering, Goebles and that whole lot would be the heroes of the nation.
Losers don't define anything. They're at the mercy of the winners. This is not sports I'm talking about. Winner/loser is indeed a property of a relationship, but it is the winner that decides how that relationship will be remembered, as I explained above. As I said: Winners write history, and had the nazis won, for instance, history would be very different.
