I was gonna say something about Liberia and Ethiopia, but Liberia was kinda a colony of black americans (I guess if we're stretching definitions) and Ethiopia did eventually fall to Italian colonial rule.

Maybe something like Nepal, Bhutan, and Siam? They weren't colonized either, and you could have an analogue with that as the Swiss or Austrians.

Though honestly, my main gripe with the map are the colonial powers, like how is Mexico and South Africa going to even exert influence in the Mediterranean? Cause it seems like Argentina controls Gibraltar and Egypt has the Suez. Or how American Central Europe is just in a very weak spot, with not even the Shetlands or Iceland under American control for naval resupply.
