The Leverage Illusion: Why Threatening War While Negotiating Peace Keeps Failing

The United States has spent the past three months doing something remarkable: it has simultaneously extended an olive branch to Tehran and brandished a stick large enough to start a war. On 29 May, Secretary of State Marco Rubio publicly offered an extension of the bilateral ceasefire memorandum of understanding. Twenty-four hours earlier, Defense Secretary Pete Hegseth unveiled a $1.5 trillion defense plan that named Iran — explicitly — as the scenario the Pentagon is now structuring its force around. Somewhere in between, the Treasury Department announced another round of sanctions targeting Iran's oil sector and financial networks. This is not coherence. This is the diplomatic equivalent of a man negotiating a raise while holding a live grenade with the pin half-pulled.

The contradiction is not incidental. It reflects a calculated theory of leverage: that the credible threat of military force will extract concessions that diplomacy alone cannot. That theory has been tested before — against North Korea, against Venezuela, against Cuba — and it has consistently produced the same result. The targeted state digests the threat, concludes that the costs of actual military action are too high for Washington to absorb, and then uses the space created by that calculation to extract exactly the concessions the threats were supposed to prevent.

The Ceasefire That Was Never Really a Ceasefire

The current US-Iran dynamic has its roots in the ceasefire framework negotiated earlier in 2026. That framework, now approaching its expiration date, produced an odd outcome: both sides gained from the pause. Iran extracted partial sanctions relief and the unfreezing of some sovereign assets — a tangible economic reprieve that the clerical regime used to stabilise its domestic position. The United States gained a suspension of Houthi Red Sea attacks that had been costing the shipping industry billions and humiliating the US Navy's deterrence credibility.

Neither side achieved its objective. Iran did not get sanctions removed. The United States did not get a verifiable cap on enrichment. The ceasefire became, in effect, a mutual timeout — each side taking what it could from the pause and waiting for the other to blink first.

The latest reporting indicates both parties are near a memorandum of understanding that would extend the ceasefire framework. That is, on its face, good news. But the conditions attached to that extension tell a different story. Iran has insisted on what it calls its sovereign right to enrichment — language deliberately calibrated to be non-negotiable, because it touches the regime's core self-understanding as a nuclear threshold state. The United States, meanwhile, has responded with new sanctions, new military posturing, and new statements from the Pentagon chief suggesting that strikes remain on the table. The message to Tehran is incoherent: extend the deal, but we're also preparing to hurt you.

The Kazakhstan Gambit

Kazakhstan's offer to host Iran's enriched uranium on its territory is the most interesting diplomatic move in this sequence and the least discussed. The proposal would effectively move Iran's nuclear material beyond its own borders — a real-world reduction in breakout capability — in exchange for a face-saving formula that allows Tehran to claim it has not capitulated to American demands. It is a creative solution that addresses the core structural problem: Iran wants the prestige and leverage of a near-complete enrichment capability; the United States wants verifiable limits on that capability. Host the material externally and both sides get something.

That such a proposal is on the table suggests there are officials inside the US interagency process who understand that military pressure is not moving the needle. It also suggests that the pressure-and-negotiate cycle is being sustained for reasons that have more to do with domestic American politics than with any realistic assessment of what actually moves Tehran.

The timing of Hegseth's $1.5 trillion posture review — arriving while talks are still nominally active — is not coincidental. It is meant to signal to Iran that the cost of refusal continues to rise. But Tehran has watched American military deployments in the Gulf for decades. It has watched US carrier groups, F-35 deployments, and Defense Secretary visits to Saudi Arabia and the UAE. Each round of escalation has been followed by diplomatic engagement. The pattern is readable, and Iran is reading it.

The Structure of the Mistake

What is happening here is not complex. The Trump administration — like several administrations before it — appears to believe that the combination of economic pressure, military positioning, and diplomatic availability creates a forcing function that compels the other side to capitulate. In practice, it creates a bargaining environment in which the targeted state simply waits for the political window inside Washington to close.

Iran's calculation is structural, not ideological. The clerical regime has survived maximum pressure from the Trump administration's first term, survived the targeted killing of its most powerful military commander, and survived years of covert sabotage of its nuclear programme. It has concluded, probably correctly, that a full-scale US military strike carries political and operational costs that no American administration — Republican or Democrat — is willing to absorb. That is not weakness on Iran's part. It is a rational assessment of the correlation of military forces and the domestic politics of extended Middle Eastern warfare.

The administration may have calculated that hardball gets deals. The evidence suggests otherwise. Every round of new sanctions, every new military statement, produces exactly one outcome: it deepens Iranian resolve, gives hardliners inside Tehran additional ammunition against any figure inclined to make concessions, and narrows the space available to Iranian moderates who might otherwise argue that a negotiated outcome is achievable. The people being hardest hit by this approach are not in Tehran. They are in the State Department's negotiating rooms, trying to explain to their counterparts that the United States is serious about both a deal and a potential attack simultaneously.

What Would Actually Move This

The honest assessment is that the current framework — ceasefire-plus, sanctions-plus, military-plus — is the maximum achievable outcome given the structural constraints both sides face. Iran will not abandon enrichment entirely. The United States will not tolerate a nuclear-armed Iran. Both sides know this. The question is whether the gap between those positions is bridgeable through the kind of creative diplomacy that produced the Kazakhstan proposal — or whether it is simply too large, and the cycle of pressure and response is what the region is stuck with for the foreseeable future.

What would actually move this is difficult to identify, but one element is clear: the threat of military force is not leverage. It is noise. What creates genuine diplomatic space is a credible commitment by the stronger power to walk away from the table — a willingness to accept the costs of the alternative. Every administration since Nixon has struggled with this basic problem in dealing with regional powers that have learned to read American domestic politics better than American diplomats would like to admit.

The $1.5 trillion posture review, the new sanctions, and the ceasefire extension are not contradictory signals. They are the same signal, repeated: we are trying to coerce you into accepting terms you have already decided are unacceptable. The only question now is how long both sides maintain the fiction that this process is leading somewhere.

—

This publication's coverage of the US-Iran nuclear talks has consistently foregrounded the gap between stated US openness to diplomacy and the structural pressure the same administration applies through sanctions and military posture. The dominant wire framing — which treats the ceasefire extension as a genuine diplomatic success — obscures the fact that both the extension and the threats are part of the same non-strategy.
