This metaphor does not map. Apple, Microsoft and Google all compete in some areas and cooperate in others. Applying a martial metaphor, especially attempting to map the players onto WWII is not illustrative or illuminating.

It's a playful representation of one key lesson.

Yahoo is definetely the US! It joined the British and it's influence might be crucial

That could work - Yahoo is US, Microsoft is UK (and traditional Western Europe). AT&T could be Italy, Motorola is Eastern Europe. Nokia makes a lot of sense as Japan since they seem to have their own set of priorities but are kinda cooperating with Android (Google)...

Thank you for trivializing a war my grandfather fought in and died. You should be ashamed of yourself.

Just kidding. I'm still trying to figure out who Japan would be..

You scared me for a second. The Japan-equivalent is tough to figure out. Maybe HTC, Sony, Nokia...not sure yet.
