The realignment is less about globalism vs nationalism + multi-polar world and more about creating a tolerance for expansionist nationalism whereby we establish an agreement with major powers to divide up the world for open conquest, with Russia, China and the United States all operating in their respective "sphere of influence"

I think its proponents imagine a world where Russia slowly reassembles territories it lost in the '91 and maybe China takes Taiwan with some short wars and the United States just chills out. In practice the United States will likely aggressively pursue its interests in North, Central and South America as well as the Middle East and do so in a destructive fashion. We can also see people manufacturing consent on various male-audience podcasts for a hot war along the Mexican border in the name of destroying the cartels. The idea that an 8% or even 16% budget cut the pentagon could somehow neuter our ability to project power at our doorstep is naive.
