To an almost miraculous degree, the world is free of the risk of Great Power conflict. The world seems to be increasingly integrated from the cultural and economic perspectives, Great Powers (rising and otherwise) seem to be more interested in joining the world system than not, and not a one seems interested in igniting any sort of cold war. The Great Powers seem to have bought into non-zero-sum paradigm of international relations. (Or have they actually bought into that?)
Most wars seem to have been displaced to the periphery of the world system. Relatively low-tech insurgencies seem dominant, sometimes locally based and sometimes depending on foreign sponsorship, frequently marked by the commission of atrocities against subject civilian populations, some of these insurgencies seeing effective outside intervention, some not, and most remaining of only humanitarian interest to outsiders. (Or have they remained durably displaced?)
Has war become outmoded as a latent threat in international relations, at least at the core of the world system? Or does it have some potential yet for renewed chaos?
