The ongoing US-Iran nuclear talks in Pakistan highlight a significant shift in US foreign policy under President Donald Trump. Key officials like Secretary of State Marco Rubio and Vice-President JD Vance are notably absent from negotiations, with figures like Jared Kushner and Defence Secretary Pete Hegseth taking leading roles. Rubio, who holds dual positions as Secretary of State and National Security Adviser, has opted to remain close to Trump in Washington, reflecting a broader trend where the State Department's traditional role in diplomacy is diminished. Instead, negotiations are increasingly handled by a select group of presidential allies. JD Vance's absence aligns with this trend, as his focus remains on domestic political matters rather than international diplomacy. The involvement of Kushner and Hegseth indicates a growing reliance on the Pentagon in diplomatic efforts, a departure from the State Department's historical leadership role. Analysts suggest this centralization of decision-making within the White House represents a significant evolution in US diplomatic practices.
