If Midway would have “turned” out “differently”(Japs TAKE Midway) then Pearl Harbor would have been FINISHED as a forward base and the US Navy would have had to return and fight the war from the US West Coast. The War in the Pacifice would have EASILY gone into 1947 or 1948.
By then the Soviets probably would have been in the fight and would have staked their claim to at least half of Japan after the war's conclusion.
