U.S. National Security officials say Iran is not living up to a “memorandum of understanding” following further U.S. military strikes on Iran. Speaking the morning after the strikes, U.S. Ambassador Mike Waltz said the United States retaliated after Iran struck a vessel in the Strait of Hormuz. Waltz frames the action as a response to what the U.S. describes as Iranian aggression and as part of ongoing enforcement of the terms of the understanding between the two sides. The reporting describes the situation in the Strait of Hormuz as the immediate trigger for the latest exchange of actions. The U.S. position presented in the coverage is that Iran’s conduct falls short of agreed commitments, while the strikes are characterized as retaliatory measures rather than stand-alone actions. The sources emphasize the timeline connecting the vessel attack in the Strait of Hormuz to the subsequent U.S. strikes on Iran and Waltz’s assertion that Iran is failing to comply with the understanding.
