How US Capitalism Uses Nationalism

From 1945 to 1990 we were told a great struggle pitted capitalism against socialism/communism (chiefly the USSR and China). Yet still today, US leaders demonize Russia and China despite the end of communism in the USSR and a huge growth of capitalist enterprises in China. The explanation lies in US capitalism's long history of using nationalism (i.e. foreign dangers) to justify tax-payer funded government actions to protect, subsidize, and support major capitalists' dominant position in the US economy.
