What was the main reason for allies decision to defeat Germany and Italy before defeating Japan?

Answer 1

The main reason for the Allies' decision to defeat Germany and Italy before Japan was due to the fact that Germany and Italy posed a greater threat to the Allies than Japan did. Germany and Italy had a much larger military presence in Europe and posed a greater risk to the Allies' security. Japan, on the other hand, was located in the Pacific and posed a much smaller threat to the Allies.
