Iran’s National Security Chief Declares U.S. Departure and Israeli Collapse Inevitable

Iran’s Supreme National Security Council Secretary Ali Larijani declared that America will leave the region and the Israeli state faces inevitable collapse, according to statements attributed to him in parliament on September 29 ^[1][2]. The remarks came as the U.S. Secretary of State warned of serious consequences for Iran should it attack American interests ^[3], underscoring the escalating rhetorical temperature between Tehran and Washington.

Larijani, appointed to his position by President Masoud Pezeshkian with Supreme Leader Khamenei’s confirmation on August 5, 2025 ^[4], told parliament that neighboring countries will ultimately remain in the region while America departs. “That day will be a day of regret,” he said, according to reports ^[1][2].

The statement reflects the regime’s standard playbook: maximalist rhetoric aimed at domestic audiences and allied factions while strategic flexibility operates at lower levels. Larijani’s appointment itself signaled pragmatism – he represents the faction willing to negotiate nuclear terms and manage international relations – yet his parliamentary performance demonstrates the political necessity of hardline posturing even for figures known to favor diplomacy.

The timing matters. U.S. Secretary of State Marco Rubio had just warned that Iranian threats to American interests carry consequences, specifically citing recent developments in Britain where Iran allegedly sought to acquire drones, missiles, and conventional weapons ^[3]. U.S. Ambassador to Israel Mike Huckabee countered with his own rhetoric, claiming Iran has 47.5 years of making false threats it never intends to execute ^[5].

What Larijani’s statement reveals is the regime’s calculation that it must maintain deterrent messaging – the appearance of willingness to act – while managing the reality of constrained options. Iran’s economy continues contracting under sanctions pressure. The rial has weakened further. Housing costs remain beyond reach for ordinary Iranians. Yet the security establishment cannot appear weak before hardliners who control significant institutional power.

The Supreme National Security Council itself sits at the intersection of these pressures. It coordinates policy across the IRGC, the Foreign Ministry, and intelligence services – factions that often pull in different directions. Larijani’s appointment suggested the pragmatist faction had gained ground post-Raisi. His parliamentary statement suggests that ground remains contested.

For the regime’s stability calculus, this creates a persistent tension. Maximalist rhetoric satisfies the ideological base and the IRGC’s institutional interests. But it narrows negotiating space with the Trump administration, which has signaled it will not tolerate what it views as Iranian threats. The regime cannot afford escalation it cannot sustain, yet cannot afford to appear capitulating to pressure.

What this tells us about the regime’s stability is that it remains trapped between two audiences: the hardline faction that demands confrontational posture, and the economic reality that demands de-escalation. Larijani’s dual role – pragmatist with institutional power, yet compelled to deliver hardline rhetoric – may be precisely the kind of contradiction that defines Iran’s next phase.
