I'm not sure I follow this completely. The phrase was coined in Sweden around 1900, then people like Haushofer - who some think was basically the mastermind/writer behind Mein Kampf - took it and made it an excuse for "lebensraum", as later Putin would blame geopolitics on the breaking up of the Sovjet Union...?
As in the interwar era, geopolitics has become a buzzword that brings with it a contagious idea. Geopolitics should be recognised as what it is: an attempt to understand the world by people and countries that believe they are losing out. As in post-1919 Germany, it looks like an appealing way of explaining a newly chaotic world to the confused. The real danger is that this mode of thinking appears so attractive that it poisons everyone else’s politics too. The haunted world of Haushofer, and of the Hartschimmelhof, is a monument to a confusing response to confusion: and a grim warning.
