A fragile two-week truce between Washington and Tehran faces imminent collapse driven by a violent internal power struggle rather than external military pressure. Hardline Revolutionary Guard commanders are rapidly consolidating control under Mojtaba Khamenei, threatening to purge any moderate factions seeking a diplomatic off-ramp.

The February 28 decapitation strike that killed Ali Khamenei did not just eliminate Iran's supreme authority; it obliterated the regime's established chain of command [1.1]. Verification of the immediate fallout confirms a rapid internal power shift. With former IRGC chief Mohammad Pakpour and dozens of senior officials dead in the rubble, a vacuum opened. It was immediately seized by a surviving network of radical Islamic Revolutionary Guard Corps (IRGC) commanders. Now operating under newly appointed chief Ahmad Vahidi, these hardliners have decentralized their command structure. Intelligence assessments indicate this militant wing is utilizing the fragile two-week truce with Washington solely as a tactical pause to consolidate power, actively preparing to purge any faction advocating for a permanent ceasefire.

This militarized takeover directly neutralizes the civilian government's diplomatic maneuvers. President Masoud Pezeshkian and Foreign Minister Abbas Araghchi have attempted to construct an off-ramp, publicly floating conditional terms to end the conflict, including a halt to US-Israeli strikes and sovereignty guarantees. However, their authority appears entirely nominal. Intercepted communications and ground-level source reports suggest IRGC loyalists view the civilian administration's negotiation efforts as treasonous. While Pezeshkian and Araghchi recently made highly publicized, low-security appearances in Tehran to project state unity, the reality behind closed doors is a violent internal struggle where moderate voices are being systematically silenced.

The definitive proof of entrenched militancy emerged during the April 9 40-day memorial for the late supreme leader. A written address attributed to his successor, Mojtaba Khamenei, explicitly dismantled any remaining diplomatic frameworks. Mojtaba remains unseen, with unverified reports citing severe injuries from the initial February strikes, leaving it unclear if he authored the statement or if it was dictated by IRGC handlers. Regardless of the author, the directive was absolute: Iran "will not forfeit its rights" and considers its proxy networks a "unified entity". By threatening a new operational phase in the Strait of Hormuz, the memorial address served as a binding policy shift. It confirmed that the radical military apparatus has hijacked the state, making an internal regime collapse a far more imminent threat to the truce than external military pressure.

• Mojtaba Khamenei's 40-day memorial address cemented the regime's militant posture, threatening escalation in the Strait of Hormuz and effectively killing moderate off-ramps.

Intelligence assessments and regional analysts indicate a systematic purge of pragmatists who advocate for maintaining the fragile two-week truce with Washington. Officials pushing for a negotiated off-ramp are being branded as traitors by the Islamic Revolutionary Guard Corps (IRGC), effectively criminalizing diplomacy. The internal witch hunt threatens to dismantle the very channels needed to prevent the region from sliding back into total war.

The threat extends far beyond political sidelining; it involves physical elimination. Hooshang Amirahmadi, president of the American Iranian Council, recently warned that moderates seeking a deal with the Trump administration risk being "most likely eliminated" as regime fractures deepen. The IRGC, emboldened by Mojtaba Khamenei's ascent following the February 28 airstrike that killed his father, views any concession as capitulation. Figures like Foreign Minister Abbas Araghchi—known for his technical negotiation skills—and allies of President Masoud Pezeshkian are operating under intense surveillance. Internal security forces are leveraging the wartime environment to settle old scores, framing engagement with the West as an act of treason punishable by death.

This violent internal power struggle exposes a fatal flaw in the current diplomatic landscape. The initial phases of the war already wiped out several senior officials whom Washington quietly viewed as potential pragmatic dealmakers. Now, the surviving institutional moderates, including networks tied to former Foreign Minister Mohammad Javad Zarif, are being systematically silenced by the hardline faction. Without these political buffers, the ceasefire rests on a razor's edge. If the IRGC successfully liquidates the remaining pragmatists, the institutional authority required to sign and enforce a lasting peace agreement will vanish entirely.

• Hardline IRGC factions under Supreme Leader Mojtaba Khamenei are actively targeting Iranian moderates, labeling those who support US negotiations as traitors.
• Intelligence and regional experts warn that pragmatists face the imminent threat of physical elimination, which could permanently destroy Tehran's capacity to negotiate a lasting peace.

Regional intelligence assessments directly contradict this optimism. Classified Israeli defense briefings warn that the current IRGC-dominated apparatus is the most extreme iteration of the regime yet. Intercepted communications reviewed by regional analysts show no signs of ideological moderation. Instead, Israeli intelligence indicates surviving hardliners are exploiting the ceasefire window to execute a violent internal purge, systematically dismantling any remaining moderate factions capable of negotiating with the West.

The analytical gap between Washington and Tel Aviv complicates the immediate security landscape. While US diplomats search for pragmatic elements within the Iranian political structure, regional operatives report those networks are actively being erased. Israeli defense officials caution that the IRGC’s internal consolidation under Mojtaba Khamenei represents a rapid militarization of the state, not a stabilization effort. The immediate unknown is how long the White House will maintain its diplomatic holding pattern before acknowledging the intelligence pointing to a hardline resurgence.

The two-week truce brokered in Islamabad is fraying at the edges, threatened less by external pressure than by the Islamic Revolutionary Guard Corps (IRGC) flexing its muscle to secure dominance in Tehran [1.5]. Following the February 28 death of Ali Khamenei, his son Mojtaba is rapidly consolidating power, flanked by hardline commanders eager to eliminate internal dissent. The Khatam al-Anbiya headquarters has publicly confirmed that Iranian armed forces remain fully mobilized, keeping a tight chokehold on the Strait of Hormuz. For the IRGC, maintaining a wartime footing is a calculated domestic strategy to sideline pragmatists seeking a diplomatic exit.

Public warnings from the Guard’s naval command leave minimal runway for de-escalation. Recent statements broadcast across state-aligned media indicate the IRGC is finalizing operational preparations for a "new order" in the Persian Gulf, cautioning that the strategic corridor "will never be the same". Spokesperson Ali Mohammad Naini has been blunt, declaring that Iranian forces are "waiting" for US naval escorts to enter the waterway. This rhetoric is not merely performative; it is a clear signal to rival factions within the regime that the military apparatus dictates the terms of engagement, and any deviation toward compromise will be treated as treason.

The immediate casualty of this internal posturing is the global energy supply. The blockade of the Strait of Hormuz, where authorized maritime traffic has dropped by 90 percent, remains the hardliners' most potent bargaining chip. The IRGC has explicitly declared an end to its "self-restraint," threatening infrastructure linked to the United States and its regional allies. Whether Mojtaba Khamenei can rein in these commanders—or if he is actively encouraging their brinkmanship to cement his authority—remains a critical unknown. If a rogue commander pulls the trigger to prove ideological purity, the ceasefire will instantly collapse, plunging the region back into a devastating conflict.

• Aggressive public declarations from IRGC commanders, including threats of a "new order" and an end to "self-restraint," severely elevate the risk of an accidental or intentional strike that could break the truce.
