How a destroyed Kriegsmarine changes Japan's war choice

British forces released from the German threat would first crush Italian naval resistance and then strengthen deterrence in the Far East.

Question

If Sea Lion destroys the Kriegsmarine, does the extra Royal Navy strength deter Japan from entering World War II?

Short answer

Possibly, after Britain first uses the released forces to defeat the Italian fleet and then shifts substantial naval power toward Asia.

Notes

The Mediterranean remains the Royal Navy's immediate priority even after Germany loses its surface fleet. Britain could concentrate extra carriers and escorts against the Regia Marina rather than sending everything straight to Asia. If that concentration neutralizes the Italian battle fleet, far more modern ships become available for the Far East. The timing and visibility of that transfer could materially alter Japanese calculations about entering the war.
