Well, it'd be easy for Germany in HOI3. Since Germany is usually the aggressor that actually provokes WWII, it can just refuse to light the spark. Germany can still win the game by influencing all nations to join up with the Axis powers.
It might be harder for the UK, but if you look at the event triggers, you might be able to find some way to game the system. If I had any HOI game, I'd try it out myself.
