I have thought about this, and given the amount of pro-Fascist sentiment in Western Europe, WWII probably wouldn't have happened. Germany would probably have gotten away with taking Austria, Czechoslovakia, possibly the lands forfeited to France after WWI and at least part of Poland.

The world would look VERY different to today. Assuming Japan stuck to their neck of the woods, the USA probably would never have gotten to be a super power (given it was WWII that really catapulted them into that category). The UK may still have reasonable parts of the empire. The super powers would probably be Germany, USSR and a lesser extent, UK, Japan.

This is the stuff of alt-historical fiction.

EDIT: apologies for straying off topic but I couldn't resist.
