US presidents lack unilateral authority to declare war on Iran, requiring congressional approval under Article I of the Constitution—a step not taken since World War II amid high political costs and focus on Ukraine, China, and domestic priorities. Recent Middle East escalations drove trader caution: Iran's October 1 ballistic missile barrage on Israel prompted US defensive aid and deployments, followed by Israel's October 26 airstrikes on Iranian missile sites, with President Biden urging restraint to avoid wider conflict. US airstrikes continue against Iran-backed Houthis disrupting Red Sea shipping, but these proxy actions fall short of war declarations. The November 5 presidential election looms as a potential pivot, with candidates signaling varied foreign policy postures toward Tehran.
