The administration has not articulated a unifying endgame for the conflict, instead hailing the degradation of Iran’s military capabilities.

Domestic reaction and casualty framing

Polls show broad disapproval of the war in Iran, underscoring political risk for lawmakers backing or opposing the conflict.
