I asked the Palin parrot what she thought of the Japanese invasion of Alaska (which, by the way, is a genuine WW2 incident... )
BTW - Have you heard a story that ancient ainu artifacts have been found in the Aleuitian islands - indicating links between Japan and Alaska that go back for centuries? Someone told me this when I visited a kitschy Ainu "village" in Hokkaido. I haven't had the chance to check up on that story yet.
