Plenty of these right-wing "anti-imperialists" are against US involvement in Ukraine because they support Russia as a capitalist, socially conservative project that they truly believe is allied with the American conservative movement. They see contemporary Russia as a model to emulate. When the US state abandons the Russian front and attempts to aim the totality of their resources at China, these right-wing coalitions are gonna buy 100% into it and abandon any of the anti-imperial politics that they've pretended to have. Anticommunism and racism will be their open objective and settler-leftists calling for allyship with them will have helped build their platform. If we ally with these fucks, all we're gonna have is a more legitimized AmeriNazi movement.
