Is the United States still the world’s unipolar power, or has the global system entered a multipolar, or even non-polar phase? This chapter examines the evolving international order, with a particular focus on China as the main rival to U.S. dominance. China’s rise across economic, military, technological, and diplomatic domains signals a transformative shift in global power. Just as Florence became the center of innovation and trade during the Renaissance, this study positions the Middle East as a potential hub in the emerging world order. It argues that regional and global dynamics are now deeply interconnected, influenced by crises such as the 2008 financial collapse, mass migration, prolonged conflicts, and the erosion of Western cohesion. These developments collectively reflect the uncertainty surrounding the future of U.S. leadership and the broader global balance of power.
