The right is just very, very liberal.

Preach. Pretty much all the major conservative policies -- small government, anti-regulations, free economic markets, individual liberty -- are literally textbook 19th-century Liberal ideals.

The one (key) area they differ is in terms of nationalism: a classic liberal wouldn't much care for "the nation" as a concept; they'd rather laws/jurisdictions/trade/administration to be, if not the same between different territories, at least "fungible" between them.

But conservatism through the 20th-century, and all the more so into the 21st, leaned heavily on nationalist rhetoric and propaganda to secure votes, which has left them in a different place now, ideologically.

Or fascist versus classical liberal for short.

The fascist state -- Nazi Germany -- was authoritarian; the US is far from that yet. But Nazi Germany does offer an interesting parallel in this sense: that state was socialist (or at least, a "mixed economy") but privileged the idea of "the nation". It's a contradiction in terms: you can't support the brotherhood of man while also favouring your own clutch of brothers living behind an arbitrary marker line.

But that's what "nationalism socialism" as an ideal was about (that's why, also, it descended so readily into genocidal racism).

The conservatism that's emerged in 2016 is dealing with a very similar contradiction. "National liberalism" (to give it a mirror name) must behave both protectionist and globalist, must be against business interference but in favour of special (even bespoke) business subsidies, must support international profiteering but oppose international production, must be pro-borders as applies to workers but anti-borders as applies to finance or trade.

And that's just as contradictory a position as "nationalism socialism" ever was.
