Unfortunately, they all agreed to the provision in the LoN constitution, and several are abusing it besides Siberia, meaning it won't be going anywhere. Most don't seem to care much, either, outside of (probably) the Nordic Union. Remember too that this same measure is in the otl UN constitution.

Not to say that others don't recognize the other states, mind. Most nations do, and should the Siberians go after any of them outside of Central Asia, things would happen against them.
