Doing something analogous to what you’re saying should happen could have prolonged the Second World War by years. Doing the opposite of what you’re suggesting but much sooner could have shortened the Second World War by years. Germany could only afford to get anything done because it was able to loot the countries it invaded during the appeasement era, and only able to manufacture military equipment at the scale necessary to invade France etc. because it was permitted to scale up manufacturing during the appeasement era. It’s nearly universally accepted that the appeasement era cost far more lives than would have been lost had France and Britain intervened during the initial invasion of Czechoslovakia as it could have been enough to entirely prevent the later invasions of Poland and France.
