In recent decades, full-scale wars and cold wars were often regarded as remnants of history, valuable primarily as lessons on the dangers of unchecked rivalry and ideological confrontation. Many believed that the modern world, shaped by institutions and economic interdependence, had moved beyond such conflicts. Yet, these assumptions now appear increasingly tenuous. Today, the dynamics of great-power competition and regional instability suggest that the world has not left these patterns behind but is instead witnessing their resurgence in new forms. The growing rivalry between the United States and China has been described as a ‘Cold War II’, evoking comparisons to the ideological and strategic tensions of the mid-20th century. At the same time, discussions of a potential ‘World War III’, once confined to speculative fiction, have entered the realm of serious analysis among policymakers and academics. These concerns are not abstract.
