Alliance replaces the Japanese threat to Australia and New Zealand

For Australia and New Zealand, Japan's entry on Britain's side would improve security without immediately removing distrust. Japanese forces would pass toward the European war instead of threatening the Pacific Dominions, strengthening their reliance on Britain and the Commonwealth. Australian and New Zealand food exports could also supply a Japan increasingly committed to armaments production. With the war far away, their industries would have more time to expand and absorb combat lessons without the same pressure to rush development.
