In strategic terms, a regime’s downfall often results not from military defeats but from the sudden collapse of its illusions. Tehran fits this description, for it is a theocratic regime founded in the late 1970s that still relies on the mindset, tools, and standards of that era – as if time has stood still.
In fact, the regime’s survival has often resulted not from its own strengths but from others’ calculations. For years, Iran served as a predictable adversary in Western deterrence strategies, a vocal enemy with a manageable pace, and it was easier to contain than to eliminate.
But history rarely sustains regimes built on repeated slogans, and chants like “Death to America,” “Death to Israel” and “Curse on the Jews” reveal a lack of alternative policies. When enmity defines governance, the regime cannot retreat without undermining its legitimacy.
From its start, the regime has used rhetoric that incites hostility toward the United States, Israel, and Jews as part of its core identity. This method fueled internal mobilization and guided foreign policy. Over time, it afforded little room for de-escalation or adjustment, and a system rooted in constant confrontation is difficult to handle without rising costs. Many analysts argued early on for stricter deterrence and containment to limit its impact across the Middle East.
If the regime is so fragile, why has it lasted? The mullahs have long benefited from a delicate balance. Some adversaries fear the chaos of its total collapse. Inside Iran, people often dread the unknown more than the status quo. The regime has also turned external pressure into a mobilization tool. This equilibrium, not inherent power, has prolonged its existence.
Regimes fall from errors at critical times
Regimes fall not just from weakness but from grave errors at critical times. For Iran, the mistake lies in an accumulation of escalations that overturned the rules.
Directly attacking Israel with missiles and drones shattered the long-standing proxy war model, and pushing Tehran-linked militias to expand attacks on Israel converted peripheral conflicts into multi-front battles. At the same time, increasing uranium enrichment in open defiance elevated the nuclear issue from a diplomatic matter to an immediate security threat for opponents. Brutally suppressing domestic protests undermined internal stability just as the regime escalated external confrontations.
Any one of these steps might have been survivable, but their simultaneous occurrence constituted a trap difficult to exit from after the first major blow. US President Donald Trump articulated this logic in an April 2025 statement reported by Reuters: “Iran has to get rid of the concept of a nuclear weapon. They cannot have a nuclear weapon.”
When Iran’s supreme leader, Ali Khamenei, warned that a US attack could spark a regional war, Trump replied: “we’ll find out whether or not he was right.”
If Tehran falls, the scenario would begin with targeted strikes on command centers, disruption of operations rooms, and breakdown of military communications. Neutralizing defenses and communication hubs would deprive the leadership of visibility before ending its capacity to fight. With dispersed decision centers among religious leaders, security forces, the Islamic Revolutionary Guard Corps and civilian officials, any delay could become decisive, and the regime would then unravel internally.
The fall of Tehran would alter the Middle East more than missiles alone; the theocratic mullahs’ collapse would upset power balances and leave Iran-backed networks without central guidance, funds or strategy.
Dormant issues in places like Lebanon, Iraq, and Yemen would reopen, with local power balances changing after the loss of Iranian support. Regional security, energy, and shipping calculations would adjust.
A primary source of ongoing tension would vanish, and this would signal not just the end of a flawed dictatorship but the dawn of a new strategic era in the Middle East.
