What is the latest possible POD for the French and British being able to defeat Hitler's Germany alone without the Soviet Union or America
A PoD at the very start of the Battle of France is probably enough. All you need to do is stall the German momentum for a few days and let the French get themselves back together, and the Germans will be ground down.
Umm the German army had 2 million men in it, by that time the British and French cannot grind them down by themselves (the sides had more or less numerical parity during sickle cut)
Probably Munich; in conjunction with the Czech's the Entente could beat Germany's still very very small field army (plus the west wall was a lot less built up) without any special difficulty (assuming the French decided they where willing to take casualties, and employ every bit of their armor and air force)

But I find it hard to imagine, with the Germans so determined to knock them out with explosive warfare.
