US President Donald Trump claimed on June 10 that the American naval blockade of Iran is "the most successful blockade in the history of naval warfare," saying the country is rapidly becoming a "failed nation" unable to pay its military or meet its financial obligations, posting on Truth Social.

The posts, published within an hour of each other, mark one of the most forceful public statements yet from Trump on the status of the US campaign against Iran, coming amid a collapse in nuclear negotiations that Washington had been pressing Tehran to conclude and the ongoing rising tensions between the two countries over the alleged shot down helicopter over the Strait of Hormuz. The remarks are the latest indication that the White House is tightening pressure on Iran as diplomatic channels stall.

"Nothing gets through unless we want it to. It is a steel wall," Trump wrote, adding that Iran is "doing zero business" and failing to pay its armed forces. In a striking closing line, he wrote "Lots of oil is getting out. Praise be to Allah!"

In a separate post, Trump declared Iran's military "a complete and total mess," asserting that its navy and air force "don't even exist anymore" following what he described as total defeat. "Iran is all talk and no action. The Bully of the Middle East is DEAD!!!" he wrote.

Trump also levelled criticism at Tehran over the pace of negotiations, saying Iran had "taken too long to negotiate a deal that would have been great for them" and would now "have to pay the price."

The posts did not provide evidence to substantiate the claims about the blockade's effectiveness or the condition of Iran's armed forces. Iran has not yet responded publicly to the statements.

"They've taken too long to negotiate a deal that would have been great for them, now they will have to pay the price!!!" Truth Social, June 10.

Prior to Trump's social posts, a senior Iranian parliamentary official praised the downing of an American military helicopter in the Strait of Hormuz, calling the unnamed fighter responsible a "hero" and vowing to honour them publicly, ILNA reported on June 10.

Ibrahim Rezaei, spokesperson of the National Security and Foreign Policy Commission of the Iranian parliament, wrote on his personal social media page that the act amounted to "another slap on Satan," invoking a phrase used in Iranian official rhetoric to describe strikes against American or Israeli forces.

The statement gave no details on when the incident occurred, the type of helicopter involved, or the circumstances of the downing. There was no immediate response from US military authorities.

"We kiss the hand of that fighter who, in the Strait of Hormuz, delivered another slap on Satan by downing an American helicopter," Rezaei wrote. "We will celebrate him as a hero."

On the same day, Iranian parliament speaker Mohammad Bagher Ghalibaf commemorated senior military commanders and scientists killed in what he described as three "imposed wars" against the United States and Israel, naming the country's most senior Revolutionary Guard figures among those who fell, ILNA reported on June 10.

Ghalibaf said Iran's defence capabilities and scientific output had continued unimpeded despite the losses, and that "every act of aggression has been answered decisively and without delay."

He framed the current confrontation as the third in a series of "imposed wars," placing it alongside the 1980-1988 Iran-Iraq war in Iran's official narrative of national resistance.

"The first, second and third imposed wars showed the world that the path to conquest and victory passes through steadfastness and martyrdom," Ghalibaf wrote. "Nations have been awakened and wills have been fortified."
