U.S. Foreign Policy and Military

President Donald Trump has deployed senior Pentagon leadership into front‑line diplomatic roles, sending U.S. Central Command chief Adm. Brad Cooper — in full dress uniform — into indirect nuclear talks with Iran in Oman on Feb. 7 while relying on Army Secretary Dan Driscoll as a key negotiator in Russia‑Ukraine peace discussions. Cooper’s presence comes as the USS Abraham Lincoln carrier strike group and other U.S. forces mass in the region, and Trump warns that if Tehran does not agree to a nuclear deal, “the consequences are very steep.” Former officials and analysts are split: some say using active‑duty commanders in diplomacy reflects an overreliance on the military and marginalizes professional diplomats, while others note past precedent for generals in arms‑control talks but call the Army secretary’s role more unusual. Analysts like Michael O’Hanlon see Cooper’s participation as meant to intimidate and signal resolve more than to add negotiating heft, while others argue his battlefield expertise could help assess risks if talks fail. The move underscores how the administration is personalizing and militarizing high‑stakes negotiations on both Iran’s nuclear program and the Ukraine war, raising questions about escalation risks and the sidelining of the State Department.
