Trump's Iran Credibility Problem

“After six months of war with Iran, President Trump has a credibility problem. His blustering threats, alternating with claims of imminent peace and victory, are doubted by friends and foe. Will his new threat this week on Truth Social of the "MOST CRUSHING ECONOMIC OPERATION EVER TAKEN AGAINST ANY COUNTRY!" be different?

 

By now the world will have to see it to believe it. No President has yet climbed the Iran sanctions ladder with China, moving from the isolated "teapot" refineries that buy Iran's oil to the Chinese state-owned enterprises that support them. Nor has any President given Dubai an ultimatum to shut down Iran's illicit financial network and meant it.

 

"ANY country that allows its financial institutions, businesses, airports, or government entities to provide any type of lifeline to Iran will itself face TREMENDOUS Economic Consequences," Mr. Trump wrote Wednesday. "Oil smuggling, swap lines, cash transfers, exchange houses, ship registries, front companies -- It all needs to stop NOW. You know who you are."

 

They do, which may be why the United Arab Emirates pre-empted Mr. Trump with its announcement on Tuesday: "All trade, commercial exchanges, and financial transactions with Iran have been halted until further notice."

 

The question is whether all of this is a headline or a policy. Only the latter, which Treasury Secretary Scott Bessent says he'll soon lay out, would give Tehran reason to fear. While Iran admits the U.S. blockade has driven its oil exports to near-zero, Dubai-Iran trade never leaves the Persian Gulf. The U.S. Navy doesn't touch it.

 

If that trade is now ending, "this could be even more significant than the [U.S.] embargo," writes the Foundation for Defense of Democracies' Miad Maleki, who led the U.S. Treasury's Iran sanctions campaign until last year. Iran can't replace Dubai and the U.A.E., on which the regime depends for as much as 80% of its foreign-currency inflows and about a third of its imports, plus payment intermediaries and sanctions-evasion infrastructure.

 

Mr. Maleki calls Dubai "Iran's window to the world economy." Its daily direct flights, large Iranian diaspora and unique financial ecosystem allow the Islamic Revolutionary Guard Corps to procure goods and repatriate revenue.

 

It is no small ask of the Emiratis to cut off their dangerous and much-larger neighbor, especially when the U.S. hasn't been able to protect them fully from Iran or restore free passage in the Strait of Hormuz. The U.A.E., America's best Gulf ally during the war, may also fear that a financial crackdown could spark capital flight from Russia and others.

 

If Mr. Trump acts on his word, the Emiratis have far more to fear from secondary U.S. sanctions. The test will lie in what happens to Dubai's Iran-linked exchange houses, money-service businesses, trade companies and beneficial-ownership networks, as well as the movement of cash and high-value goods. Will flights be scrutinized for bulk-cash and gold smuggling? A halt to gasoline and refined-product exports to Iran would be felt immediately.

 

In the day since Mr. Trump's announcement, the value of Iran's currency has fallen significantly, exceeding 1.9 million rials to the dollar. "Nearly all of the regime's economy is dependent on the U.A.E. network," the Iranian dissident journalist Mojtaba Pourmohsen says. Transactions run through intermediaries who are often children or relatives of Revolutionary Guard or Intelligence Ministry figures, he adds.

 

There's more to be said about Iran's networks in Turkey, Iraq, Qatar and Pakistan, as well as in crypto. But the key is that trade cutoffs, unlike sanctions, are felt immediately.

 

Iran may lash out militarily in response, targeting Gulf energy again, and the U.S. will have to be ready with a firm response.

 

 "We are going to collapse this regime," Mr. Bessent said Thursday. Economic pressure can make survival more difficult for the regime, but it will take more resolve and consistency than Mr. Trump has shown in the past six months.” [1]

 

Iran can target America’s military assets in the region too. The Iranian swarms of precise missiles and drones are not going anywhere.

 

Iran possesses a substantial arsenal of ballistic missiles, cruise missiles, and uncrewed aerial vehicles (UAVs) capable of threatening United States military personnel, bases, and naval assets deployed across the Middle East.

Regional Threats

•           U.S. Bases: Installations in countries like Iraq, Syria, Qatar, the United Arab Emirates, and Bahrain remain within range of Iranian missile and drone capabilities.

•           Naval Assets: Warships operating in the Persian Gulf, the Strait of Hormuz, and the Gulf of Oman face persistent exposure to anti-ship missiles and fast-attack craft.

•           Air Defense: U.S. and allied forces rely on layered defense systems, such as Patriot and Terminal High Altitude Area Defense (THAAD), to intercept incoming aerial threats.

Strategic Context

•           Asymmetric Warfare: Iran uses low-cost drones and massed missile volleys to challenge high-end integrated air defense systems.

•           Proxy Networks: Allied militias across the region provide Tehran with additional means to pressure U.S. positions without direct state attribution.
