The two wars with Iran have significantly degraded its ability to produce a nuclear weapon in the near term. But they may also have dramatically increased Tehran’s motivation to acquire one over the longer term.

That is why the key question is no longer simply whether Iran resumes enrichment, but what it intends to achieve if it does. If Tehran decides to rebuild its enrichment program, it may conclude that returning to the old threshold posture no longer makes strategic sense, and that the purpose should instead be to cross the Rubicon toward 90 percent enrichment.

For all the attention given to Iran’s missile arsenal or its ability to threaten the Strait of Hormuz, its so-called “economic nuclear weapon”, there is ultimately only one capability that could fundamentally change Tehran’s calculation about its vulnerability to future attack: an actual nuclear deterrent. Iranian leaders look at North Korea and understand that lesson very clearly.

This does not mean that Iran has decided to build a bomb. There are major unanswered questions about how Tehran assesses the risks, whether it believes it still has the technical and operational capacity to move toward weaponization, and whether it thinks it could do so without being detected and attacked again.

But Iran will inevitably have to reassess its nuclear strategy. And if its leadership concludes that nuclear weapons are now necessary for regime security, then despite the damage inflicted by Israel and the United States, Iran may still retain pathways, technically and practically, to pursue that objective.

That creates the central paradox of these wars: a campaign intended to push an Iranian nuclear weapon further into the future may also have strengthened the strategic logic in Tehran for eventually trying to acquire one.

If that debate has not already taken place inside the Iranian leadership, it almost certainly will. The public debate emerging from Iran itself already gives us reason to watch that question very closely.
