I am just interested in history. I joined because of the Battle of Midway, an underrated victory.

Date of three battles:
Midway: First week of June 42
Stalingrad: Aug 42 to Feb 43
El Alamein: Oct 42 to Nov 42

Assumption:
Japan wins the Battle of Midway with no losses of an carrier. Minor airplane losses.

Question:
How would have this impacted the
Battle of Stalingrad
and the Battle for El Alamein?

Would the US delivered less amount of important material to the Soviet-Union, because they required the resources to defend California?

What about the British 8th Army?
