The 2026 US-Iran conflict serves as a “Suez Moment” for American hegemony, exposing the terminal decline of the post-1945 rules-based order. As US security guarantees fracture, global allies are shifting toward “major hedging” and regional autonomy to protect their own energy and economic interests. In this vacuum, Pakistan has transitioned from a frontline state to a pivotal mediator, leveraging the Islamabad Talks to define a new era of transactional multipolarity. This shift prioritizes terrestrial connectivity and local stabilization over the unilateral dictates of a distant hegemon.
