From my knowledge of history, the winners god's is always right, just as history is written by the victor. That latter part includes the former, and goes far beyond what we usually acknowledge. It's not only that the victor's reasons for a war are considered just over the loser's. The values of the victor, his cultural framework, are used to judge the loser's and the rest of the world's. And history is written from his viewpoint. It's a meta victory.
