This right here. Right-wing politics require oppression of an underclass or other. The first steps would be likely be to turn inward and mass murder and/or imprison/enslave dissidents and minorities. This is not sustainable, however, as there are only so many that can be oppressed in one place without hitting critical mass, and that's not even getting into the economics or other factors.

So, like all other right-wing governments, they would be forced into expansionist/imperialist action. This would probably start with trying to annex a swath of Mexico, but could, if the politicians are the "true believer" type, rather than pragmatic sociopaths, it could well be the Midwest. In the first case, we likely end up with a new narco-state with oil fields in cartel hands, and a long, intractible insurgency. In the latter, the RoT gets curb-stomped by NATO and/or other coalition forces. Either way, lots of non-combatants suffer unnecessarily.
