If France holds out until 1941

A prolonged French defense undermines Germany's economy and makes Italian entry far less likely, while changing Japan's calculation through a stronger British naval position.

Question

Do Italy and Japan still join Germany if France does not fall until 1941 or later?

Short answer

Italy may stay out because Germany no longer looks certain to win quickly; Japan still calculates its options but faces a less distracted Royal Navy.

Notes

If Germany remains tied down on the Western Front into 1941, it cannot turn east on schedule and may face economic collapse. Italy's opportunistic entry depended on an apparently quick German victory, so a prolonged French defense may keep it neutral. Without an Italian war, Britain avoids major Mediterranean losses and can station more ships in or near the Indian Ocean. Japan must then weigh expansion against a much less distracted Royal Navy.
