Hang on a sec…
- The article states the goal is to 'force Tehran to re-open the Strait of Hormuz,' yet it fails to clarify if the Strait is currently fully closed or merely restricted, leaving the scale of the crisis undefined.
- The claim that the US will seize commercial ships in 'international waters' lacks a discussion of the legal framework or potential for retaliatory 'tanker war' scenarios that historically follow such actions.
- The piece relies entirely on 'unnamed US officials' via a secondary report (WSJ), providing no official confirmation for an action that would constitute a major escalation in international law.
