What conditions and actions would resolve the conflict between Iran and the USA?
A deal is possible, but only if both governments can frame concessions as victories at home.
Schmidt and Machiavelli converge on the same structural point: sanctions without clear terms for relief harden Tehran rather than move it, and military capacity matters only as leverage to open talks, not as a substitute for them. Keynes anchors this in 1919, when reparations with no viable payment path collapsed Weimar rather than disciplined it. Mandela adds that each side must be able to sell the deal domestically; at Groote Schuur in 1990, he gave the apartheid government language it could defend, and that formula held.
Ibn Khaldun and Ben-Gurion mark the limit. Ibn Khaldun argues that the Islamic Republic's core constituencies are still cohesive enough that external pressure consolidates rather than fractures the regime. Ben-Gurion insists that any agreement leaving Iran a viable path to nuclear weapons is not a resolution; Israel absorbs the risk alone if that path remains open.
Confidence summary: The council reaches a Type 1 verdict with moderate-to-high confidence on the structural conditions for a deal, but genuine disagreement persists on whether any achievable deal is actually sufficient.
1. The core argument
The sharpest insight is not that a deal is hard. It is that both governments have built their domestic legitimacy on the conflict itself, which means the primary obstacle is not technical but political. Every member of this council, across radically different historical vantage points, identifies the same first move: each side must be given language it can sell at home as a victory. Without that, no inspection regime, sanction-relief schedule, or security guarantee survives the next election cycle in either capital.
The secondary structural problem is the sanctions architecture. Pressure without stated terms for relief does not compel; it consolidates. The Revolutionary Guards control the black market that sanctions create. The Iranian population absorbs the cost; the hardliners absorb the benefit. A deal must therefore offer Iran a credible economic path, not as a reward for good behaviour, but as the mechanism by which Iranian reformers can demonstrate that engagement works. Military capacity remains necessary, not as a tool of coercion but as the condition that makes negotiation credible. Without it, Tehran has no reason to sit down. With it alone, Tehran has no reason to concede.
2. How each member frames it
Helmut Schmidt draws on his 1979 refusal to join the American position during the hostage crisis as more than a moment of allied friction; he treats it as proof of concept. Economic strangulation with no exit ramp hardened Tehran then and, on his reading, has hardened it repeatedly since. What the card could not fit is Schmidt's insistence that reciprocity must be visible at each stage. In his management of Ostpolitik, concessions were sequenced so that neither Moscow nor domestic German conservatives could credibly claim the other side had taken everything. The same architecture is required here: no single grand bargain, but a ladder of reciprocal steps, each small enough to survive a domestic backlash on either side.
John Maynard Keynes makes the Paris 1919 analogy load-bearing in a way his card only sketched. His deeper point is institutional: punitive arrangements that cannot physically be honoured do not discipline the target; they transfer power to whoever can operate outside the formal economy. In Weimar, that was the nationalist right. In Iran, it is the Revolutionary Guards. Keynes would push negotiators to design the economic relief component first, not last, because a deal that leaves Iran's formal economy strangled will be arbitraged by the same actors the deal is meant to constrain.
Nelson Mandela refuses to treat trust as a precondition. This is the counterintuitive move his card gestured at but could not develop: at Groote Schuur, the negotiating framework assumed bad faith and designed around it rather than waiting for good faith to arrive. His specific contribution to the Iran-US framing is the concept of "face-preserving staging," each concession announced in sequence, with enough time between steps for both governments to narrate it domestically as strategic progress. He is candid that this requires the US to accept that Iran will spin the deal as a defeat for American hegemony. That is the price of a durable agreement.
Ibn Khaldun is the council's most structural voice, and the least reassuring. He argues that the Islamic Republic's core asabiyya, the solidarity binding the Revolutionary Guards, the clerical establishment, and their dependent constituencies, remains intact. External pressure does not fracture what is still cohesive; it fuses it. His limit condition matters: a deal becomes negotiable only when the regime's internal cohesion has already begun to crack from within, from economic exhaustion, generational change, or elite defection. He does not say that moment has arrived. He says watching for it is as important as designing the deal itself.
Niccolò Machiavelli separates the appearance of strength from its reality with more precision than his card allowed. His 1502 observation of Cesare Borgia yields a specific prescription: the US must sustain credible military capacity visibly enough that Iran cannot treat the negotiation as a delay tactic with no downside, while simultaneously constructing a formula in which Iran's acceptance of nuclear limits reads in Tehran as a strategic achievement rather than foreign-imposed surrender. The fox and the lion must operate together. He is explicitly sceptical of deals that humiliate the other party's leadership, not on moral grounds but because humiliated leaderships find ways to renege.
David Ben-Gurion accepts Machiavelli's framing on appearances but insists Israel operates in a domain where the distinction between appearance and reality collapses. His peripheral strategy of the 1950s, treating pre-revolutionary Iran as a counterweight to Arab state power, was rational precisely because it was unsentimental. That logic collapsed in 1979, and no American security guarantee has compensated for it since. His challenge to the council is specific: any agreement that leaves Iran with a viable technical path to a nuclear weapon within a defined breakout window is not a resolution. It is a postponement, and Israel, not Washington, absorbs the consequences of a failed postponement.
3. Where the council agrees
The most surprising point of agreement is that military pressure and diplomatic engagement are not alternatives; they are complements. Every member, including those most sceptical of American policy, accepts that Iran negotiates only when it cannot ignore the cost of not negotiating. Schmidt held that deterrence creates the condition for dialogue, not a substitute for it. Machiavelli is explicit. Even Mandela, who most strongly emphasises the negotiating table, structured the South African transition with security forces visibly intact.
The council also agrees, unanimously, that the current sanctions architecture has misallocated its costs. The population bears them; the Revolutionary Guards benefit from them. This is not a contested empirical claim among the members. Keynes and Ibn Khaldun reach it from opposite directions and arrive at the same place. Any resolution requires designing economic relief as a structural component, not as a diplomatic sweetener added at the end. Finally, all six members agree that domestic political framing on both sides is not secondary to the substantive terms; it is the binding constraint. A technically sound deal that neither government can defend at home is not a deal. It is a countdown.
4. Where the council splits
The split is clean and neither side is wrong. Schmidt, Keynes, Mandela, and Machiavelli believe a deal is achievable now, provided the staging and framing conditions are met. Ibn Khaldun and Ben-Gurion doubt it, for different reasons that point in the same direction. Ibn Khaldun argues the Islamic Republic's internal cohesion has not yet reached the fracture point at which external terms become attractive to its leadership. Ben-Gurion argues that even a well-staged deal, with reciprocal concessions and face-preserving language, leaves Israel exposed if Iran retains any technically viable path to a weapon. The first group believes the structure of a deal can be built now. The second believes the preconditions for a durable deal do not yet exist, and that a premature agreement is worse than a continued standoff.
5. For a policymaker to decide on
The choice is this: pursue a staged partial agreement now, accepting that Iran retains some enrichment capacity below a defined threshold, with the domestic and allied risk that entails, or hold for a more comprehensive settlement that requires either deeper internal change in Iran or a military outcome that forecloses its nuclear path. The first option is achievable and fragile. The second is more durable and may not arrive on any predictable timeline. Only the policymaker can weigh which risk their government can absorb.
