Yet, despite the familiar language of escalation, much of what is unfolding appears closer to brinkmanship than preparation for war. And Iran represents the very definition of such a war. For a president whose political brand is built on restraint abroad and disruption at home, a war with Iran would contradict the central logic of his foreign policy narrative. A war with Iran – larger, more capable and more regionally embedded – would almost certainly follow a similar, if not more expensive, trajectory. A war with Iran would jeopardize all of these.
