By George Friedman : We are at the 70th anniversary of the end of World War II in Europe. That victory did not usher in an era of universal peace. Rather, it introduced a new constellation of powers and a complex balance among them. Europe’s great powers and empires declined, and the United States and the Soviet Union replaced them, performing an old dance to new musical instruments. Technology, geopolitics’ companion, evolved dramatically as nuclear weapons, satellites and the microchip — among myriad wonders and horrors — changed not only the rules of war but also the circumstances under which war was possible. But one thing remained constant: Geopolitics, technology and war remained inseparable comrades.
