Vice President JD Vance, a former Iraq War veteran, has been involved in selling a war in Iran, despite his anti-interventionist stance and hawkish views on Iran. Vance, who has previously endorsed President Donald Trump for his 2024 White House bid, has argued that the U.S. must be prepared to prevent Iran from developing or deploying nuclear weapons. While Trump and his administration have provided various reasons for starting a war without congressional approval, Vance has focused on Iran's nuclear capabilities. The war and his role as vice president could complicate his political future in a Republican Party that has less appetite for foreign intervention.
