The book "Foundation of Geopolitics" was released in 1997 in Russia and it details what Russia's political role in the world should be. The part about America goes like this:
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".
Like you don't want to be a tinfoil conspiracy theorist, but I think we're way past that now. Specially since we had the hacking and bots reports from the 2016 election. Makes you wonder how many accounts in twitter and social media overall are just russian bots.
