Read Aleksandr Dugin book and it all makes sense. It's part of the geopolitical playbook.
Sowing Social Division: The book explicitly directs Russian operatives to introduce "geopolitical disorder" inside the U.S. by fueling racial, social, and religious polarization.
Exploiting the Democratic Process: While it doesn't give a step-by-step guide to voter suppression, it encourages the promotion of isolationist and extremist political groups to break down faith in public institutions, media, and the democratic process itself.
