Are the Iranians actively attempting to rebuild their capabilities, or aren’t they?
Iran is clearly rebuilding capacity across a range of military and nuclear domains, and the evidence is not subtle. From centrifuge upgrades and enriched uranium stockpiles to more sophisticated missile and drone production, the regime has been methodically restoring what it lost. That matters because capability plus intent equals a real threat to the region and to American interests.
The nuclear program shows steady technical progress, not episodic hiccups. New centrifuge models and enrichment at higher levels indicate a deliberate push toward breakout options, and facilities that were once shuttered are being refurbished or replaced. Keeping these programs on ice requires pressure, not platitudes.
Missile development is moving in parallel with nuclear work, and Iran’s test programs are not for show. Longer-range ballistic missiles and more accurate medium-range systems expand Tehran’s reach and raise the stakes for partners like Israel and Saudi Arabia. When missiles pair with precision-guided munitions or drones, the ability to threaten critical infrastructure becomes much more credible.
Unmanned aerial systems are a big part of the rebuild story, especially since Iran has turned drone production into a scalable industry. Those drones are exported to proxies and used in asymmetric attacks, multiplying Iran’s influence without exposing Tehran to direct retaliation. That export pipeline is a strategic multiplier that changes how conflict looks in the Middle East.
Iran’s network of proxies and allied militias accelerates capability rebuild without putting Tehran in the line of fire. Hezbollah, Iraqi militias, Houthi forces, and others receive missiles, drones, training, and targeting data, creating layered fronts that complicate responses. That approach lets Iran extend power while maintaining plausible deniability.
Sanctions have worked when enforced, but sanctions fatigue and creative evasion have reduced their sting. Ship-to-ship transfers, deceptive flagging, and third-party middlemen have kept revenue flowing and materials arriving despite official prohibitions. If enforcement slips, so does the leverage that slowed Tehran’s programs in the past.
Scientific depth and institutional memory matter more than a single treaty or inspection regime. Iran kept personnel, know-how, and covert supply lines intact even when facilities were degraded, which makes a genuine rollback difficult to achieve quickly. Reconstituting capability is therefore faster than starting from zero.
Diplomacy has a role, but only when backed by credible deterrence and a willingness to deny key inputs to Tehran’s programs. Cheap concessions or symbolic deals invite technical work to accelerate behind the scenes. Real negotiations require leverage, not surrendering leverage for the hope of cooperation.
The administration’s posture matters. A mixed record of enforcement and engagement sends mixed signals, and Iran reads those signals clearly. Strong, predictable policy that combines tough sanctions enforcement, targeted military presence, and robust support for regional partners is what changes Tehran’s calculus.
Congressional and allied pressure helps sustain long-term effort, because resumes of enforcement matter more than headlines. Laws that tighten sanctions, improve interdiction, and increase defense aid to partners create a durable framework for containment. Those measures also narrow Tehran’s options for rebuilding at scale.
Intelligence and rapid response capabilities reduce the window Iran needs to convert technical advances into operational threats. Timely strikes on key nodes, public exposure of evasion networks, and coordinated allied pushback raise the cost of rebuilding. When deterrence is credible, many avenues of capability restoration become uneconomical for Tehran.
The basic question—are they rebuilding—has a clear answer: yes. That means policy should be forged around denying Iran the lifelines it needs and backing up diplomacy with enforceable pressure. The alternative is letting capacity grow while hope fills the gap where resolve should be.
