What are the known motivations or justifications for the U.S. and Iran exchanging strikes?

The U.S. claims its strikes against Iran-linked targets respond to threats against its personnel, specifically after Iran-backed militias attacked U.S. forces in Iraq. Officials cite self-defense under international law and the need to protect regional alliances.

Iran says its attacks on U.S. military assets in Iraq retaliate for the January 2020 drone strike that killed Qasem Soleimani, a top Iranian commander. Tehran frames this as self-defense and a move to restore deterrence against U.S. aggression.

The U.S. seeks to maintain Middle East influence, counter Iranian power, and keep Iraq and the Gulf stable. Iran aims to push back against U.S. influence, shield its allies, and assert its own military and political presence.

Final: U.S. justification is self-defense and interest protection; Iran’s is retaliation and deterrence.
