Gee, you act like there was something wrong with that. Are you going to say that the United States and other (classically) liberal democracies were wrong to be in conflict with the Soviet Union and other totalitarian regimes and political systems?
At the same time, whether (or when) such conflict is good or bad has not a thing to do with the analogical phenomena of competition for reproductive representation between individuals within a species. Even if we concede the applicability of the analogy, we would still be committing the naturalistic fallacy (arguing from "is" to "ought").
Ok, you're on record believing that war is a necessary means of progress. You and Adolf would have been good buddies.
