US-Iran tensions feature ongoing limited US military strikes and a naval blockade of the Strait of Hormuz amid Qatar-mediated talks, yet no congressional declaration of war has occurred despite months of operations. President Trump has signaled openness to a nuclear and Hormuz agreement that could avert escalation, describing renewed attacks as highly unlikely if progress continues, while Secretary of State Rubio noted demands remain far apart. Recent developments include fresh strikes on Iranian air defenses in early November and Iranian proposals for limited waterway reopening tied to sanctions relief. Formal declarations remain rare in modern US conflicts, with actions typically proceeding under executive authority rather than Article I congressional action, keeping trader-implied odds for an official declaration by year-end near 2 percent. Key upcoming factors include further negotiation rounds and any post-midterm shifts in congressional posture.
