What is Britain had not entered WWII

[Seamus Fermanagh]

That's different than what the discussion topic suggests...that Britain does not enter the war at all. I can't see that happening, but Britain suing for peace after Dunkirk is certainly within the realm of possibility.

I thought I addressed that. I was pointing out how a British DoW might have been found underwhelming by AH in terms of influencing his decision (which was the Brit intent behind the declaration of support for Poland), since he really thought he would win on the continent and England would bow out rather than keep up the fight against such odds. The not entering the war angle, as I said, would have been both France and England not guaranteeing Poland. I cannot see either government making such a statement solo at that juncture.

However, there's still the Far East, and Japan is going to eliminate Singapore when it takes the DEI...they simply have to for strategic reasons. Then what? Granted the alliance between Germany and Japan was mostly a paper affair, but what does Germany do when Britain is forced to declare war on Japan? I can't see them not doing anything to hold up their end of the alliance

I have to agree here. Had Malaya been independent the Japanese might have bypassed Singapore and Hong Kong in favor of the DEI only, but Malaya with its resources was always on their to do list. Since the Brits controlled it, they would have likely gone after it regardless.

However, it is not impossible that the entire Japanese attack would have been re-thought if Britain had NOT been at war in the West and DID ramp up forces, defenses, and RN deployment to Singapore. That is, as you will quickly note, a LOT of 'ifs.'
