‘Security for All or None’ – Iran Signals Gulf-Wide Consequences as US Escalates

Iran has declared that maritime security in the Persian Gulf and the Sea of Oman will be enforced on a reciprocal basis, following Washington’s announcement of a naval blockade targeting Iranian shipping.

Lieutenant Colonel Ebrahim Zolfaghari, spokesperson for the Khatam al-Anbiya Central Headquarters, described the move as a natural extension of Iran’s sovereignty, stressing that defending territorial waters is a “natural and lawful duty.”

“The Armed Forces of the Islamic Republic of Iran explicitly and decisively declare that the security of ports in the Persian Gulf and the Sea of Oman is either for everyone or for no one,” he said.

Tehran reaffirmed that passage through the Strait of Hormuz will be regulated under what it called a permanent mechanism implemented by its armed forces. Vessels affiliated with adversaries “do not have and will not have the right to pass,” while other ships will be allowed transit under Iranian regulations.

Iran also condemned the US move as “illegal” and an act of “maritime piracy,” warning that any threat to its maritime security would have broader regional consequences.

“If the security of the ports of the Islamic Republic of Iran… is threatened, no port in the Persian Gulf and the Sea of Oman will be safe,” Zolfaghari emphasized.

US Blockade and Iranian Mockery

The escalation follows US President Donald Trump’s announcement of measures to interdict vessels entering or leaving Iranian ports after 21 hours of inconclusive negotiations between US and Iranian officials in Pakistan.

US Central Command confirmed that the blockade, set to take effect Monday, would target vessels linked to Iranian maritime activity, while allowing passage for ships not connected to Iran.

Washington has maintained that its proposal in the negotiations represented a “final and best offer,” as US Vice President JD Vance put it, despite the talks collapsing without agreement. Trump has reiterated the demand that Iran abandon uranium enrichment entirely, framing it as a necessary guarantee against nuclear weapons development.

Iranian officials, however, have not merely rejected the blockade — they have openly ridiculed it.

Parliament Speaker Mohammad Baqer Qalibaf mocked the economic consequences of the move, warning that Americans could soon “be nostalgic for $4–$5 gas,” suggesting the policy would backfire domestically.

At the same time, Iranian Navy Commander Rear Admiral Shahram Irani dismissed Trump’s threats as “ridiculous and laughable,” framing them as detached from realities on the ground, while stressing that Iranian forces maintain full oversight of US military movements in the region.

The tone emerging from Tehran has been consistent: the US move is not only illegal and escalatory, but also strategically misguided.

The confrontation has already reverberated across global markets, with oil prices rising sharply amid fears of disruption in the Strait of Hormuz, a critical artery for global energy supplies. Asian markets also declined as concerns grew over the potential impact on trade and energy imports.

The current standoff follows a two-week ceasefire brokered on April 8 after weeks of direct confrontation. Negotiations in Islamabad ultimately failed, with Iranian officials citing excessive US demands and a lack of trust in Washington’s commitments.

Iran is now framing the situation in broader strategic terms, signaling that any attempt to isolate its ports will not remain contained. By declaring that maritime security in the Gulf is “for all or for none,” Tehran is warning that escalation in Hormuz could extend beyond a bilateral dispute and affect the entire region.
