I think as white demographics in Western countries continue to decline, and more and more of government and infrastructure is taken over by non-whites, you will see a "consolidation" effect as whites who consciously and subconsciously do not want to live around/under non-whites move to favorable countries en masse and consolidate their various white ethnic backgrounds into large, white identitarian communities, similar to "white castling", Orania, etc. The large expat communities in various SEA and South American countries will begin to pool their resources and form parallel societies similar to what has occurred within our own countries with Muslims/Indians/Blacks. Obviously, in time the survival of these communities, and countries that will still have strong white majorities, will depend on their ability to defend themselves from the authorities of the countries that they find themselves in/globohomo/outsiders.
It isn't ideal, and it certainly is no consolation for the loss of Europe, but whiteness, European identity, culture and the history of our peoples will survive through them.
Also, cozy up to the Amish, for they shall inherit America.
