The UK and France should have backed the Confederates. Imagine a permanently divided American continent just fighting each other instead of creating misery, wars of aggression, coups and civil wars throughout the world.
Also, the US definitely wasn't on the right side of World War I. There was no right side there, only wrong sides, and the problem was that America allowed one wrong side to win overwhelmingly and dictate terms to the defeated party, which were harsh enough to create extreme resentment and not harsh enough to prevent the resurgence of German power. Exactly what Machiavelli said NOT TO DO.
