My take away from the recent convulsions of jingoism culminating in Iran is that it will come to be looked back upon as a turning point in the American right: White MAGA Americans have turned their back on the prospect of remaining the demographic majority, in favour of being a multi-racial imperial power.
Any person whose main priority was securing the future of White America would rightly say that the actions undertaken so far by the Trump admin are nowhere near close enough to change course from the impending White minority status, and that the military adventurism surrounding Ukraine, Greenland, Canada, Venezuela, Cuba, and Iran are extremely dangerous wastes of limited time and attention from the domestic demographic matters that need tending to right now.
When I think back to the events of 2016, the radicalism and ethnic nationalism of the "dissident right" have almost completely disappeared. The right-wing radicals of today in America almost unanimously fall into two camps: Zionist-friendly "Deus Vult" crusaders who want basically the same things as "Holden Bloodfeast" type neocons, and multiracial Fuentes-like chauvinists. Neither care about the preservation of the ethnic identity of the USA as a country of Europeans with a European cultural foundation.
