@Aretaku:
I think the best option the Japanese had would have been to only attack British and Dutch interests in the Pacific. Bypass the Phillipines
Since a time ago, I’m wondering about a possible what if. What if if Spain would gave Cuba independence before 1898? With no Spanish-USA war, it’s possible that or Philippines would receive independence before WW2 or maybe Spain still retains at starting (and also Guam and some others). Any case, it’s few probable that USA would attack a Japan that didn’t menace any USA’s interest. Without doubt, they would not fight for a far asian country without relation with USA
In case of a Spanish Philippines, there are 2 possible scenarios:
- Franco wins SCW and controls Philippines. As pro-axis country, Japan would not have any incentive attacking this. As much, we could see Spanish ships fighting Royal Navy in Pacific ocean …
- Republic wins SCW or SCW doesn’t happen. Many in that time saw Azaña’s government as pro-soviets (true or not, that’s another matter), so it’s possible that Japan still attacks Philippines if they see Spain as too pro-soviet (that could make Spain join european war as they would need UK’s or USSR’s support to fight Japan’s navy). Anyway, I doubt USA attacks Japan to support a so-called commie country when they failed to aid France and UK
The conclusion: Japan has no real incentive attacking Pearl Harbour, so no USA entry at war. This could mean a victorious Germany (horrible) or soviet flag in Paris (slightly less bad). I wonder if sinking of Maine leaded to Pearl Harbour and later to Hiroshima and Nagasaki :-o
