Aleksandr Dugin's 1997 textbook Foundations of Geopolitics lays out a comprehensive foreign policy plan to establish a new Russian empire. Among the points it makes:
- Destabilize America through information warfare and sowing racial division
- Separate the UK from Europe
- Assimilate Ukraine into the Russian sphere

There is currently no official English translation of the book. Neo-Nazi Richard Spencer's wife (who is Russian, which I'm sure is a total coincidence) is translating Dugin's work including Foundation.
