Tensions at the Strait of Hormuz: Diplomacy on the Edge
As a new round of nuclear and security negotiations prepares to resume across three countries, Iran's Islamic Revolutionary Guard Corps — the IRGC — is sending a clear and defiant message to the world: its missile program is not only intact, it is accelerating.
Majid Mousavi, commander of the Iranian Air Force, was filmed conducting an inspection of an active missile base, where multiple missile systems were confirmed to be operational and on standby. The footage revealed missile depots housing several categories of weapons, along with drone systems that officials say are being upgraded at an unprecedented pace. Iranian military leadership used the visit to push back against what they called foreign propaganda — specifically, claims that Iran's defense capabilities have been significantly degraded.
The inspection came amid continued threats from both the United States and Israel, who Iranian officials accuse of acts of aggression that triggered the current conflict, which erupted on February 28th.

On Sunday, April 19th, the IRGC released a statement — published through Turkish media — signaling that a reopening of the Strait of Hormuz remains possible, but only under specific conditions. Iran demands the full withdrawal of American warships from the Strait and from other positions throughout the Persian Gulf before any consideration of reopening the critical waterway.
The statement came in direct response to U.S. President Trump, who had called on Iran to open the Gulf of Oman as a precondition for a new agreement.
What followed was a rapid and revealing sequence of events. On the evening of Saturday, April 18th, Iranian Foreign Minister Abbar Araki publicly announced that Iran had agreed to reopen the Strait of Hormuz. However, within 24 hours, that decision was reversed. According to reports, the IRGC's General Staff reacted with sharp displeasure to the Foreign Minister's announcement — viewing it as an unauthorized, unilateral concession. The episode exposed a significant fault line within Iran's own power structure: the Revolutionary Guards, widely regarded as more powerful than the elected government, had not sanctioned the statement and refused to be bound by it.
Iran's position, as clarified by the IRGC, is that the Strait of Hormuz remains under Iranian authority until a formal and comprehensive agreement is reached — and that any passage through it requires explicit Iranian approval.

The situation escalated further when, following the United States' refusal to withdraw its naval forces, Iran announced it was closing the Strait once again. Iranian officials placed full responsibility on Washington for the breakdown, stating it was the U.S. — not Iran — that violated the terms of the preliminary understanding.
In the days that followed, IRGC fast-attack boats — armed with missiles — opened fire on at least three commercial vessels attempting to transit the Strait without authorizat
