The Richelieu in the Atlantic flying the swastika would not have been a good thing.

That's the mistake Hitler made that nobody talks about. He should have pressed hard for the French fleet, or at least part of it, during peace negotiations. The British would have tried hard to stop it, and indeed they actually did disable a chuck of the fleet in Africa. But if Hitler had really tried, could he have gotten a couple of battle cruisers and heavy cruisers? We'll never know.
