A strain of commentary, prevalent on both the isolationist right and the anti-interventionist left, insists on framing the military campaign against Iran as “Israel’s war.” The claim is convincing in its simplicity and serves a recognizable political function: it feeds a broader campaign to demonize Western power and delegitimize its exercise. It is also wrong. The confrontation with Tehran reflects American and Western imperatives that would demand attention even if Israel vanished from the map tomorrow.

Start with the nuclear question. A nuclear-armed Iran would pose a direct strategic challenge to the United States. It would transform the balance of power across the Middle East, trigger proliferation among Gulf states, and place the world’s most critical energy corridor under an atomic umbrella controlled by a theocratic regime. Such a development would constrain American freedom of action in the region and undermine the security architecture Washington has maintained for decades. Preventing that outcome, therefore, falls on Washington not as a favor to allies, but as a matter of its own strategic interest.
