Geopolitics has a long history but it can be defined as how, where, when and why geographical factors, physical, economic and social influence the influence of political power, the shape of international relations and the strategic decision making of states and other entities, including both private companies and other non state actors. Where and when to invest is increasingly important globally and companies often want to ensure that investments are in relatively safe/politically stable areas. Geopolitics also involves decisions and conflicts over resources - gas, oil, copper, and recently rare earth minerals. The term geopolitics was first used in 1900 by Rudolf Kjellenn a Swedish political scientist but in 1904 Halford Mackinder, a British geographer, university professor and MP wrote an influential paper called 'The Geographical pivot of history' which argued that certain key areas of the world had been historically and politically important for many centuries. Although his choice of area can be queried 120 years later, his general thesis remains influential. Today, geopolitics is as important as ever and it is possible to look at many different parts of the world where there are conflicts between states over borders, oceans and territory. The podcast briefly discusses some of these, including the south China Sea, the conflict between India and Pakistan over Kashmir, American and Chinese spheres of influence and the conflicts in the middle east involving Israel, Gaza,Syria, Lebanon, Iran, Yemen and the Gulf states. Geopolitics is of growing importance.
