Iran’s newly appointed national security adviser, Mohsen Rezaei, has warned neighboring Gulf states against cooperating with what he called President Donald Trump’s “economic war” on Tehran, vowing to prevent “a single drop of oil” from leaving the region if they do. The tough rhetoric, reported by Erika Solomon of The New York Times, signals a sharp escalation in Iran’s posture as it braces for renewed US sanctions and diplomatic isolation.
In his first major policy statement since taking office, Mohsen Rezaei — a former commander of Iran’s Islamic Revolutionary Guard Corps (IRGC) and a known hard-liner — issued a stark ultimatum to Gulf Arab states. “We will not allow a single drop of oil to leave the region if they join Trump’s economic war,” Rezaei said, according to the report published Saturday. The warning comes as the Trump administration is reportedly preparing a new round of economic sanctions aimed at crippling Iran’s oil exports, a key source of revenue for the Islamic Republic.
Rezaei’s comments underscore the deepening rift between Iran and the US-backed Gulf monarchies, particularly Saudi Arabia and the United Arab Emirates. While some Gulf states have sought to maintain neutrality in US-Iran tensions, others have deepened security ties with Washington. Analysts suggest Rezaei’s threat is intended to deter these nations from cooperating with US efforts to enforce sanctions or increase oil production to offset Iran’s diminished supply.
The warning also reflects the influence of Iran’s hard-line faction, which has grown more assertive since the collapse of the 2015 nuclear deal and the subsequent failure of diplomatic outreach. Rezaei, who was a candidate in Iran’s 2021 presidential election, represents a generation of IRGC-linked leaders who favor confrontation over negotiation. His appointment signals that Tehran may be preparing for a prolonged period of economic warfare rather than seeking a diplomatic off-ramp.
Gulf officials have not publicly responded to Rezaei’s remarks, but regional analysts note that any significant disruption to oil shipments through the Strait of Hormuz — a critical chokepoint for global crude — would roil energy markets and risk a broader military confrontation. The US Fifth Fleet, based in Bahrain, maintains a strong naval presence in the region precisely to safeguard freedom of navigation.
International observers are watching closely for any signs of follow-through. “This is classic Iranian brinkmanship,” said Dr. Karim Sadjadpour, an Iran expert at the Carnegie Endowment for International Peace. “The question is whether this is just rhetoric to pressure Gulf states, or a prelude to actual kinetic action that could spiral out of control.”
Analysis
Why This Matters
- Global energy markets at risk: Any disruption to oil shipments through the Strait of Hormuz — through which about 20% of the world’s oil passes — could spike crude prices and trigger a global economic shock.
- Regional stability on a knife-edge: A direct Iranian threat to Gulf states escalates the proxy conflict into a potential state-on-state confrontation, increasing the risk of US-Iran military engagement.
- Trump administration’s pressure campaign: The warning may complicate Washington’s effort to isolate Iran diplomatically and economically, especially if Gulf states balk at full cooperation for fear of reprisal.
Background
Relations between Iran and the United States deteriorated sharply after President Trump withdrew from the Joint Comprehensive Plan of Action (JCPOA) in 2018 and reimposed crippling sanctions. Iran retaliated by breaching nuclear limits, attacking oil tankers, and supporting proxy forces across the Middle East. Gulf states, particularly Saudi Arabia and the UAE, have historically aligned with Washington but have also sought to hedge their bets, engaging in tentative talks with Tehran.
Mohsen Rezaei’s appointment as national security adviser marks a shift toward harder-line leadership. A former IRGC commander, he is known for his role in the Iran-Iraq War and his staunch anti-Western views. His predecessor, Ali Shamkhani, was seen as a pragmatic figure who maintained backchannel communications with Gulf states and European powers. The change signals that Iran’s supreme leader may be prioritizing deterrence and pressure over diplomacy as the US campaign intensifies.
Past Iranian threats to close the Strait of Hormuz have rarely been fully carried out, but periodic incidents — such as the 2019 attacks on Saudi oil facilities and the seizure of tankers — have demonstrated Tehran’s capacity to disrupt shipping without triggering a full-scale war.
Key Perspectives
[Iran]: Mohsen Rezaei frames the threat as a defensive measure against US economic warfare, insisting Iran will not tolerate Gulf states acting as Washington’s enforcers. The goal is to raise the cost of cooperation and force neighbors to remain neutral.
[Gulf States (Saudi Arabia, UAE)]: These nations rely on secure oil exports and strong ties with Washington for security. They are caught between the desire to maintain US support and fear of Iranian retaliation. Publicly, they have not responded; privately, they may seek to balance cooperation with de-escalation.
[Critics/Skeptics]: Analysts warn that Iran’s rhetoric could backfire by pushing Gulf states closer to the US, or by provoking a US military response if threats translate into action. The risk of miscalculation is high, and the Strait of Hormuz is too strategically vital for the US to allow a blockade without a major response.
What to Watch
- Oil prices and shipping insurance rates: Any spike in premiums for vessels transiting the Strait of Hormuz will be an early indicator of real disruption.
- US naval posture: An increase in patrols or a public deployment of additional assets by the Fifth Fleet would signal Washington’s readiness to interdict.
- Gulf diplomatic signals: Statements or visits by Saudi or Emirati officials to Tehran, or public pledges to the US, will reveal whether they are choosing sides or seeking a middle path.
