Bannon is no dummy. He realizes that the only way a white nationalist will be able to take and hold power is to drive a wedge between various immigrant/minority groups. The easiest is what he's trying to do now - drive blacks/hispanics to see Asians as a threat to their own economic security. If that is successful what you'll see eventually is a white nationalist who tries to get black support. Sounds crazy but that person is going to try and make the argument that blacks and whites need not be enemies. He will even make an argument that affirmative action style policies should be kept in place for blacks only (due to legacy of slavery/Jim Crow). Anything to create division between blacks/hispanics (hispanics high birth rate is what scares white folks). Next 10-15 years politically gonna be crazy IMO. Lot of competing forces and things feel unstable.
