The blockade of Iranian ports began at 10:00 a.m. Eastern on Monday, and by every observable measure it proceeded on CENTCOM's terms, not the president's. Ships transiting the Strait of Hormuz to non-Iranian destinations were not impeded. Vessels departing Iranian ports after the deadline were intercepted and turned back. The toll-paying interdiction that Trump ordered in international waters was nowhere in evidence. [1]

This paper reported Sunday on the gap between Trump's "any and all Ships" declaration and CENTCOM's narrower operational directive. Twenty-four hours later, the gap has not closed. It has hardened into operational fact.

The Notice to Mariners issued by CENTCOM, first flagged by maritime analyst Sal Mercogliano on X, specified that neutral vessels in Iranian ports had until 1400 UTC on April 13 to vacate. [2] After that window, any ship entering or departing an Iranian port would be subject to boarding, inspection, and potential seizure. The notice said nothing about the broader Strait. It said nothing about toll-paying vessels. It was the blockade CENTCOM described on Saturday — not the one the president announced on Truth Social.

The White House has not issued a clarification. Press Secretary Karoline Leavitt referred reporters to the Pentagon. The Pentagon referred reporters to CENTCOM's April 12 statement. [3] No one in the chain of command will say whether the president's words carry operational weight or whether CENTCOM's interpretation superseded them.

Three specific divergences identified in Sunday's reporting remain unresolved. First, scope: Trump targeted every vessel transiting the Strait; CENTCOM targets only vessels bound for or departing Iranian ports. Second, toll interdiction: Trump ordered the Navy to "seek and interdict every vessel in International Waters that has paid a toll to Iran"; CENTCOM has not referenced the IRGC toll regime. Third, the word "blockade" itself: under international law, a blockade applies to a belligerent's ports, not to an international waterway used by dozens of nations. CENTCOM's framing is legally defensible. The president's is not. [4]

The operational reality confirmed which version prevailed. Reuters reported that a Greek-flagged tanker bound for Fujairah in the UAE transited the Strait without incident. [1] A Liberian-flagged bulk carrier departing Bandar Abbas was hailed by the USS Gravely and ordered to reverse course. Iranian ports were sealed; the Strait remained open.

On X, hawks argue CENTCOM's narrowing is the Pentagon undermining the commander-in-chief. Realists argue it is the military saving the president from an act of war against every Gulf ally simultaneously. [5] Neither narrative has been addressed by any official, because no official has acknowledged that the two versions differ.

The precedent deepens daily. Lincoln's Blockade Strategy Board performed a similar function in 1861, scoping a presidential proclamation down to match naval capacity. [6] But Lincoln knew about it. The current silence leaves open the possibility that Trump believes his order is being executed as stated. CENTCOM's next briefing is Wednesday. The gap remains a fact of this war's command structure, unremarked upon by the officials responsible for it.
