He understood the "power and might", of the new world, and I was making the point of military power.
I took it that the word 'supremacist' can mean military and economic supremacy, which certainly has merit in the former and can be argued coherently in the latter.
If you use the word 'supremacist' in the terms of a people, like those who belived in Aryan supremacy, you probably realize the American people are made up of heratige from every ethnic and racial heratige in the world. So obviuosly that doesn't apply, although the best dogs are mutts, not purebreds.
