The ideas of Ratzel and Mackinder have been further developed by Walter Vogel and Richard Hartshorne7. Otto Maull8 asserts that economic penetration is a perfect substitute for a real military domination and Drs. Schacht and Funk have given practical effect to this theory by preparing The ground for political conquest by economic domination in the Baltic and Balkan Regions It was Rudolf Kjeller however who first used the term 'geo-politik' and whose work "Staten som lifsform" is of utmost importance for the recent developments of geopolitics. He recognises five divisions of political science : Krato-politik-the legal organisation of the power of the state; Geo-politik-the state as a realm in space; Demo-politic-dealing with the forms of political organisation of the masses; Geo-politik-the organisation of the production and consumption of goods; and Socio-politik. The states are living organisms and the struggle for space is the main ambition of the state to become united with the soil9. Vitally strong states with a limited area of sovereignty are dominated by the categorical political imperative to enlarge their area by colonization, by union with other states or by conquests of different types. This expansion as a means of self preservation means the extermination of small states even as primitive people are isolated, exterminated or driven to the periphery in an expanding World of Culture.
