The contemporary world, marked by the emergence of new domains of cognitive and virtual warfare and the changing nature of threats, has confronted the United States with a strategic challenge. The central question of this article is: What is the nature of the new architecture of U.S. dominance in West Asia, and how is the United States’ security strategy transitioning from a heavy physical presence toward more flexible, intelligent, and network-centric models? The theoretical framework is grounded in constructivism and the emerging dimensions of power in sociology. According to this approach, power is embedded not only in military instruments but also in the ability to define the rules of the game. The research adopts a qualitative methodology with a descriptive–analytical approach, drawing data from U.S. national security strategic documents, reports by defense research institutions, and recent scholarly sources. The findings indicate that the United States has transitioned from a War on Terror strategy toward a strategic reconfiguration focused on great-power competition. This transition has four consequences: a shift in the deterrence paradigm from a predominantly military approach toward integrated deterrence; the transformation of cognitive warfare and perception management through social media algorithms into a central pillar of contemporary confrontation; the redefinition of power on the basis of artificial intelligence and emerging instruments of warfare; and the exploitation of social polarization to weaken the power structures of rivals. Accordingly, Iran’s strategy for compelling the United States to withdraw, without an understanding of these strategic transformations, is bound to fail and requires a transition from a purely military balance toward a smart existential balancing approach.
