I hope you don't mind me knocking off Hitler for story purposes.
I don't mind if you knock off Hitler for any reason.

Or just because it's Tuesday.
Britain went to full war production as did the various Dominions such as Canada, South Africa, India, Australia New Zealand and so on.
What do you suppose they'd been doing?
...Japanese forces to cross quickly into Burma and Malaya while Japanese troops in China attacked the British concession of Hong Kong. It was meagrely defended since so many commonwealth troops had been concentrated in India and Britain itself. ...Roosevelt at this time still lacked a clear casus belli
Japan would
never attack the Brits without attacking the U.S., too, given Lend-Lease (even stronger TTL, IIRC), which means attacking Pearl & P.I. to eliminate the obvious threat to Japanese SLOCs.
...New Guinea (in the last one the Australians scored a victory and prevented total occupation.
Of New Guinea? Or of Oz?

(The latter was impossible...)
Roosevelt, in a show of solidarity, sent the Pacific fleet’s battle line to the Philippines.
Without the carrier scouting force?

I find that extremely unlikely.
...declaration of war followed from Washington on February 18th 1942. The Philippines under general MacArthur resisted the attack heavily, but the aggressiveness of this assault along with the element of surprise forced him to leave for Australia
What, in a matter of days, when it took IJA over five months OTL?

He's General Schwarzenegger, now?
...not knowing of Yamamoto’s use of naval airpower. His forces clashed with Japanese planes at Leyte Gulf. The battle was short as Japanese planes attacked with torpedoes and aerial bombs against the cumbersome battleships. His ships sank Kaga and crippled Soryu
Without any carriers in company, I seriously doubt Kimmel's Battle Line ever gets within gun range, let alone sinks one carrier and damages another.
Only USS Arizona returned
Cute.
...Like the British, the switched to night time raids...
Throwing out over a decade of doctrine?

On what basis? Seeing they didn't despite heavy OTL losses...
...These raids, however, were 1000 plane raids
By what magic do they boost production so much to manage this in '41-2?
and so a German city was levelled daily
Who do you think you're kidding? This didn't happen with OTL 1944 weight of bombs, let alone '41's.
...Enterprise, Lexington and Saratoga.
Sara unharmed by IJN sub? How?
The battle line had to be restored as well and so USS Texas, New York, North Carolina, Washington, South Dakota, Indiana and Massachusetts were dispatched from the Atlantic...
All of which were too slow to operate in company with a carrier task force. Or is USN still convinced BBs dominate, despite the shellacking Kimmel took?
..to fight at Midway as the attack there had been postponed...
Without the Doolittle mission? IMO, that means there'd be no MI.
...had broken their codes and could read all of their transmissions.
That is
drastically overstating American capability in 6/42.
Not a chance. She was too small & too slow.
...replace Kaga with light carriers Shoho and Zuiho
Same as
Ranger.
...Zuikaku and Shokaku were having repairs done after having encountered carriers HMS Formidable, HMS Victorious, HMS Indomitable, HMS Illustrious and light carrier HMS Eagle which had been transferred to the Indian Ocean as they weren’t much needed in the Atlantic...
Say what?


No use to defend against U-boats? No use on their OTL duties?
...Shokaku had suffered severe damage to her flight deck due to repeated bomb hits while Zuikaku had lost half her air arm...This was the first Allied victory in a long time and was a great boost to morale and in India were going better as well.
So mauling 2 IJN CVs isn't a victory? (I'd also wonder why four RN CVs, with better deck protection & the ability to operate TSRs at night, couldn't have sunk a pair of IJN CVs with less-capable damage control and no deck armor...)
...with the brand new P-51 Mustang...
When doctrine suggests not flying escorts? And when P-38s would be more numerous?

...Douglas SBD-3 Dauntless dive bomber ...

...B-17 flying fortress ...
Not the longer-legged & heavier-bombload B-24?
And it gets no better...
I just can't let this one go...
... build the Volkswagen Beetle under license., making it a true ‘People’s Car’ which is what Volkswagen means. This design was so simple and cheap that it could easily be mass produced for little cost. Even today, millions of Chinese produced ‘People’s Cars’ are still in use in China and in the Third World. This was a family car, available for only 1.000 German marks and able to achieve a respectable speed of 100 km/h. Production wouldn’t cease until the early 1980s.
To begin with, it's Type 1, not Beetle; the factory didn't use the name Beetle or Bug til the new ('98) Beetle came out (on a Golf platform, BTW). Second, ending production in the '80s is nonsense. OTL, production lasted in Mexico til 2001; with the high demand in PRC, without the higher fuel economy & safety standards that killed U.S. imports, the Type 1 would stay in production much longer. (I daresay nothing the Soviet car industry can produce would offer real competition... I also rather doubt PRC's was any better, so the PRC Type 1s would bear the same relationship to Wolfsburg's as Ladas do to FIAT 124s...& the poor rep for "Mexican parts" would be orders of magnitude worse for "Chinese parts".
