Thanks to @barneypiccolo@lemm.ee for the following summary and turning me on to the linked excellent summary of the book.

Foundations of Geopolitics was published in 1997 by Aleksandr Dugin. It outlines how Russia can become the world’s dominant superpower without warfare. It is taught in Russia’s military officers school, Putin keeps a copy in his office, and it is Russia’s geopolitical playbook. Dugin is still closely involved with Putin and Russian intelligence, and so was his daughter, who was murdered in a car bombing that was likely meant for him.

Under the section for the United States, it says:

Russia should use its special services within the borders of the United States and Canada to fuel instability and separatism against neoliberal globalist Western hegemony, such as, for instance, provoke “Afro-American racists” to create severe backlash against the rotten political state of affairs in the current present-day system of the United States and Canada. Russia should “introduce geopolitical disorder into internal American activity, encouraging all kinds of separatism and ethnic, social, and racial conflicts, actively supporting all dissident movements – extremist, racist, and sectarian groups, thus destabilizing internal political processes in the U.S. It would also make sense simultaneously to support isolationist tendencies in American politics”.
