Sure multi racial nationalism could “work” but only in the same sense that it presently “works” in Brazil ie badly.
What would actually be best for the entire world is everyone of every race rising up and ending Jewish power.
Then we can all return to our own racial and ancestral home countries and finally live in peace.
America however is a different story because so many different groups could lay claim to it as well mixed race people would need a place to go so everyone after the Jew removal from power should sit down and peacefully carve/divide America up into separate racial zones but under the agreement we all share the resources and keep the trucks going all across the country like now delivering stuff to the various grocery and hardware/building supply stores and the like.
The Jew has sold us on the equality/brotherhood lie that we should all live together.
We should not as this only ever leads to violence and destruction as each race competes to hold the others down and dominate them and have the dominant culture.
Instead we should separate but agree to work together to keep trade/trade routes going and allow a limited tourism and vacationing into each others lands and that’s it.
The planet is big enough for all of us and big enough for us not to have to be forced to live together in such close proximity it creates cultural clashes, violence, division and hate.
The Jew enjoys all of the above as it keeps the goyim distracted while they wreck the nation and commit their crimes and their foul deeds.
