You provided no books or authors.
How about you disseminating some of the knowledge you claim to know.
Faith Hillis' Children of Rus' which I just cited is not a book? Who knew? (I know it's academically dense, but see if you can't get through the introduction.)
George Vernadsky's A History of Russia is not a book?
Russia and the Golden Horde: The Mongol Impact on Medieval Russian History by Charles Halperin is not a book?
Bloodlands by Timothy Snyder is not a book?
I've read and cited all of these and more here on FR.
Your turn. What books have YOU read? Aleksandr Dugin maybe?
