With a POD after 1901, your task is for there to be a three way cold war between:
A Czarist Russia (or successor state)
Imperial Japan
United States of America.
Hmmm...
Well, as long as Japan cools its expansionist jets and stays out of world war 2 they can hang around in a powerful position indefinately. Combine some kind of rapid entente victory in World War One (preferably with Russian reforms) and both Japan and Russia will find themselves in a strengthened position.
Time will likely bring Russian, Japanese, and American interests into conflict soon enough.
An interesting concept really.
