Europe has a very violent long history. This is due to the fact that it has very limited natural resources and land. The population density in Europe is the highest in the World. Add to this, it population is controlled by very selfish elites and groups who have insatiable greed and dangerous ambitions.
The concept of territorial expansionism is endemic in Europe. The Nazis supported territorial expansionism to gain “Lebensraum” (German for “habitat” or literally “living space”) as being a law of nature for all healthy and vigorous peoples of superior races to displace people of inferior races; especially if the people of a superior race were facing overpopulation in their given territories.
For Europeans, most of Africa is only suitable for looting resources, but African environment and its population is, considered by Europeans, unfit and hostile for colonization. This is equally true for all Asia south of Russia.
Australia; Latin America and Canada are not geographically adjacent to Europe. The remaining option for European massive territorial expansionism is only Russia.
Any weak government in Russia will allow the annexation of Ural; Siberia; and Far-Eastern Russia to Europe. Also, any policies of appeasement or defensive policies will certainly crumble against the consistent and aggressive European territorial expansionism.
The only peaceful solution to these threats to Russia is by bringing political and conceptual democratic revolutions in Europe to reverse the EU imperial ambitions.
