This uniquely interdisciplinary volume analyzes the challenges posed by the heterogeneity of the world where radically different players are crammed into increasingly limited political, commercial, social, and ecological space. The rapid rise of Communist Party-ruled China is posing serious challenges to the postwar politico-economic architecture dominated by the United States. Russia, once expected to become a partner of the liberal Western international order, has started behaving in an increasingly unilateral fashion. The developing world is more characterized by failed governance rather than convergence to liberal democracies as was hoped by many Western authors. Given links provided by low-cost carriers, the Internet, and trade and investment, we simply cannot shield ourselves from influences, whether benign or malign, from neighbors on this planet.
