President Donald Trump on Wednesday blasted the mainstream media for failing to report on the effectiveness of "the most successful Blockade in the history of Naval Warfare" in the Strait of Hormuz.

"The Fake News Media refuses to report how EFFECTIVE the U.S. Naval BLOCKADE is," Trump wrote on Truth Social, declaring that "NOTHING GETS THROUGH unless we want it to. IT IS A STEEL WALL!"

Trump said the blockade has left Tehran economically crippled, arguing Iran is "doing ZERO business," failing to pay its military or bills, and "quickly becoming a FAILED NATION."

The president's comments came as new data cited by the nonpartisan Foundation for Defense of Democracies showed the U.S. blockade and sanctions have delivered a major blow to Iran's oil exports, long the regime's chief source of hard currency.

According to FDD on Friday, Iran exported zero crude oil in May and only 2 million barrels of naphtha, equal to roughly 64,000 barrels per day.

That was down from just over 2.1 million barrels per day in February, the last full month before the war involving the United States, Israel and Iran began.

FDD said May marked the lowest export volume from Iran's energy sector in more than a decade and showed the U.S. blockade had "effectively severed the regime's primary financial artery."

The report said Washington imposed the naval blockade against Iranian ports on April 13, after Iran's closure of the Strait of Hormuz disrupted normal maritime traffic.

By the end of April, Iran's seaborne petroleum exports had fallen below 1 million barrels per day, before collapsing in May to just 3% of February levels.

Estimated Iranian export revenues in May fell below $200 million, according to FDD.

Only four small-capacity vessels reportedly bypassed U.S. enforcement, carrying naphtha cargo to China.

FDD said the remaining shipments involved tankers flagged by Cameroon, Gambia, and Panama.

The Strait of Hormuz remains one of the world's most important oil chokepoints, connecting the Persian Gulf to global markets.

The International Energy Agency says it is the primary export route for oil produced by Iran and several Gulf states, with much of the crude headed to Asia.

Trump's defenders say the blockade demonstrates the power of peace through strength by forcing Tehran's terror-supporting regime to confront the economic cost of aggression without rewarding it at the negotiating table.

"Lots of oil is getting out," Trump wrote. "Praise be to Allah!"
