What if WW2 Nations were Buffed/Nerfed

How would WWII go if the following:

Round 1:
USA – Manufacturing speed is 50% faster (still requires logistics and materials)
Britain – Has access to one USS Gerald R. Ford Aircraft Carrier (cannot reverse engineer)
Germany – Absolute Aerial Supremacy; no Nation’s airforce can stand against the German Airforce (still requires fuel)
France – Troops cannot surrender or lose morale (Does not mean troops are fierce or cannot be encircled and cutoff from resources)
Poland – Soviet Union does not invade them.
Soviet Union – Troops and logistics are impervious to the Winter (logistics themselves are not necessarily improved).
Italy – Troops move 2x fast.
China – Troops do not need to eat.
Japan – IJA troops are invincible; they cannot be damaged by guns, mortars, nukes, et cetera, but can still get tired, die from natural causes, and can no longer swim.

Round 2:
Britain – Loses its entire navy right before the war.
USA – The Confederate States of America revolt and proclaim independence in 1936. They start with the same military might as the rest of the Union (can still be outproduced). Partisans may still exist after being defeated.
Germany- Troops move 50% slower in combat (advances, operations, et cetera)
Italy – Back to WWI technology (still may have any equipment built up to 1940)
Soviet Union – 50% population loss
Poland – All Polish politicians and military personnel lose 10 IQ points.
Japan – Starts with Tokyo nuked.
France – Impossible to form frontlines.
China – Communist China and the Kuomintang do not unite and civil war is still ignited.
