The United States appointed
Nick Stewart as an adviser to its diplomatic team amid ongoing stalled negotiations with Iran over its nuclear program and sanctions relief. Notably, White House spokeswoman
Olivia Wales described Stewart as a "sharp, seasoned policy expert" who will enhance the delegation led by Special Envoy
Steve Witkoff.
Stewart's background includes previous roles in the State Department and advocacy for a hardline approach towards Tehran, promoting increased pressure through sanctions. His addition comes as the U.S. military has seen a significant surge in operations in the Middle East, with at least
12 military transport planes identified, mostly C-17A Globemaster IIIs, and support from Boeing KC-135 Stratotanker aircraft near Israel.
Negotiations, mediated by Pakistan, are complicated by conflicting demands from both sides. Recent discussions in
Islamabad failed to yield results, though ongoing willingness was noted. Notably,
Iran has proposed a 14-point plan to resolve issues within 30 days, challenging the U.S.'s positions and seeking an end to hostilities.
President
Trump, while reviewing Iran's proposal, expressed skepticism about reaching a viable agreement, referencing the need for Iran to face consequences for its historical actions. Stewart's expertise may prove crucial as both nations navigate tenuous diplomatic waters amidst increased military activities in the region.
