Twenty-seven days. That's how long the Iranian regime managed to honor the ceasefire it signed in June — the deal that lifted sanctions, turned Tehran's oil money back on, and asked exactly one thing in return: stop shooting at ships.

They couldn't do it. We've seen New Year's resolutions with more staying power than the Islamic Republic's signature. So at 4 p.m. Eastern on Tuesday, U.S. Central Command made it official on X: American forces have "resumed the naval blockade against vessels transiting to and from Iranian ports and coastal areas." More than 20 Navy warships and hundreds of military aircraft are now positioned across the Middle East — in CENTCOM's words, "vigilant, lethal, and ready."

The regime demanded permission slips for the world's shipping. It just got answered by the one navy on Earth that has never asked anyone's permission for anything.

Here's the backstory, because the press corps will spend the week calling this an "escalation," and it's nothing of the sort. On June 17, Trump and Iranian President Masoud Pezeshkian signed a memorandum of understanding that ended the first blockade — the one that ran from April 13 to June 18. Iran guaranteed commercial ships safe passage through the Strait of Hormuz and froze its nuclear program for 60 days. In exchange, Washington lifted oil sanctions and called off the Navy.

Iran took the sanctions relief. Cashed the check. Restarted the oil exports.

Then it started shooting at the very ships it had just promised to protect.

CENTCOM commander Brad Cooper laid out the tab this week: seven commercial ships attacked in seven days, with roughly a dozen crew members killed, missing, or wounded. The Revolutionary Guard actually bragged through state media about striking two "non-compliant" supertankers. Non-compliant! With a permission slip Iran had no authority to demand in the first place.

The UAE says Iranian cruise missiles hit two of its tankers in Omani waters — international water, following every rule — and killed a crewman. Then came missiles and drones aimed at the 5th Fleet's home base in Bahrain, and at American positions in Jordan, which knocked four Iranian missiles out of its airspace.

Some ceasefire. The only thing Iran ceased was pretending.

The answer landed Monday night, and it took five hours to deliver. American strikes hit military targets in Bushehr, Chabahar, Jask, Konarak, Abu Musa, and Bandar Abbas — the coastal missile batteries, drone sites, and maritime attack systems Iran uses to hit shipping, dismantled port by port down the coastline. An hour before the blockade snapped back into place Tuesday, CENTCOM announced another round for good measure.

And how is Tehran taking it? Deputy Foreign Minister Kazem Gharibabadi announced that Iran now has "no obligations" under the 14-point agreement it signed.

No obligations! Sir, we noticed. That's why the Navy is here.

Gharibabadi also complained that Washington is blocking Iran from "exercising sovereignty" over the strait. Sovereignty. Over water that belongs to everybody. That's not sovereignty, fellas — that's a tollbooth on the open ocean, staffed by the Revolutionary Guard. A protection racket with a flag.

An Iranian army spokesman went one better, declaring the Strait of Hormuz "will never be reopened through war, hostility, or acts of aggression by the United States." Which is technically true — at the current rate, Iran won't have anything left to close it with.

Trump, meanwhile, is reading Tehran the menu. "We're going to hit them very hard tomorrow night. We're going to hit them very hard the night after, and then next week it gets really bad for them," he said Tuesday. "Next week comes the power plants. Next week comes the bridges... unless they get to the table and negotiate."

He did clean up one loose end. A day after floating a 20% fee for ships wanting American escort through the strait, Trump reversed himself and said transit protection comes free. Correct call. You can't win an argument against tollbooths while operating one.

Because America has been in this exact business dispute before. In 1801, the Barbary states demanded tribute from American ships for "safe passage" through the Mediterranean — and for years we actually paid it, until the bills swallowed a humiliating chunk of the entire federal budget. Jefferson stopped writing checks and sent the Navy instead. That's why the Marines' Hymn mentions "the shores of Tripoli." Selling protection on the high seas is one of the world's oldest rackets, and gunboats have always been the cure.

There's an even closer rerun than that — same villain, same strait.

In 1987, during the Tanker War, Iran mined the Persian Gulf and attacked commercial shipping. Reagan put Kuwaiti tankers under the American flag and Navy escort. When Iran kept it up, the Navy delivered Operation Praying Mantis on April 18, 1988 — and by dinnertime had sunk or crippled roughly half of Iran's operational navy. Three months later, Ayatollah Khomeini — who had sworn to fight to the last — accepted a ceasefire he famously compared to drinking "the chalice of poison."

Here's why the sequel ends the same way. Follow the money: every barrel Iran sells leaves through the same ports the Navy just sealed, and nearly all of it goes to one deeply discounted customer — China. The tollbooth and the toll road belong to the same regime. By attacking the strait, Tehran closed its own cash register; the blockade just locks the drawer.

Which means the most important phone call of this war won't come from Washington. It'll come from Beijing, where some very unhappy official is already drafting the "knock it off" memo to his Persian supplier. When your one remaining customer tells you the shooting stops, the shooting stops.

Nobody should be cheering for a wider war — real sailors are dying on ships that were just hauling oil. But the mullahs signed a deal, banked the money, and broke their word inside a month. The blockade isn't an escalation. It's the bill coming due.

They can settle up at the table now, or after the power plants make Trump's list. Either way, the strait stays open and the tollbooth is gone — and somewhere in Tehran, somebody is already rinsing out the chalice.
