So, let's posit no Hitler in Europe; Germany rearms, at a less moderate pace and without the Uboats to challenge the UK. This lets the UK focus on east Asia, and it adopts a more belligerent tone to Japanese expansion, ultimately getting the League to impose sanctions, which America agrees to.

It strikes me that the Royal Navy would have done terribly in the pacific; nothing had the range of the Zero, its aircraft carriers couldn't hold as many planes as American or UK ships, etc. Or am I mistaken?
