- 伊朗协议可能反映出美国政府在制裁和航道管理方面做出了特朗普政府此前明确排除的让步。
- 最佳替代方案（BATNA）这一概念表明，唐纳德·特朗普总统可能接受了一份不完美的协议，因为相较于现有条款，其他备选方案似乎更糟糕。
- 伊朗在此类谈判中的行事模式取决于掌控资产相关的筹码并设定要价，而非寻求妥协。

随着围绕伊朗可能达成的协议的辩论从“是否会达成协议”转向“协议内容是什么”，评论已抢先于事实出炉。我们尚未看到协议文本。我们不清楚具体的承诺、时间表或执行机制——如果有的话。
但根据已公开的信息，美国政府似乎放弃了此前明确拒绝的一些立场——在制裁问题上，甚至在霍尔木兹海峡的长期管理问题上。
如果属实，许多人会得出结论，认为唐纳德·特朗普总统以不利条件做出了退让。
他为何会这么做？不妨思考一下谈判理论中的一个基本概念：BATNA，即“达成谈判协议的最佳替代方案”。
问题很简单：如果没有达成协议，会发生什么？这是外交官在谈判进入决策阶段时会提出的问题。
评估协议——以及替代方案
上周，谈判似乎陷入僵局。当时的关键抉择很可能是：是抽身离场，还是在伊朗的部分条款上做出让步。
BATNA理论告诉我们，如果抽身离场不会让你处境更糟——甚至能为未来的谈判增强筹码——那么拒绝一份不尽如人意的协议或许是合理的。但如果谈判失败会让你处境恶化，那么即便一份存在缺陷的协议也会变得有吸引力。
这似乎就是特朗普当时面临的争论。
支持达成协议的一方可能指出了诸多问题：海湾地区航运中断带来的日益加剧的经济压力、不断上涨的能源价格、全球市场的不确定性，以及军事升级的风险不断上升。在关键条款上让步之外的替代方案，很可能是军事升级——以及伊朗袭击海湾基础设施、进一步加剧经济压力的风险——或是随着能源需求进入旺季、供应趋紧，只能忍受对峙局面。
反对达成协议的一方可能看到了截然不同的局面：油价仍处于可控水平。美国主导的穿越海峡的海上走廊开始运作。伊朗经济因制裁和石油出口受阻而承受的压力越来越大。在他们看来，时间对德黑兰不利，而非对华盛顿。
特朗普似乎接受了前者的观点。如果目前的报道属实，他可能已经得出结论：相较于眼前的其他替代方案，一份不完美的协议更为可取。
而在伊朗问题上，还有一个超越BATNA的教训。
我会彻底去掉“替代方案”中的“替代”二字。因为通常情况下，只有一种可供达成的协议。
我在解救人质的谈判中汲取了这一教训。在人质谈判中，伊朗的行事模式很少基于妥协。它基于对筹码的掌控。德黑兰会获取有价值的东西，拒绝归还，然后设定要价。
满足要价，人质就能获释。拒绝，人质就会继续被扣押。伊朗对此深谙此道。
同样的逻辑似乎也塑造了此次谈判。
伊朗通过威胁商业航运和能源流动，有效掌握了全球最重要航道之一的主动权。核心问题从来都不是华盛顿是否认可伊朗的条款。问题是华盛顿是否愿意为重新开放海峡支付所需的代价。
如果没有可行的替代协议，此类谈判中的筹码便偏向伊朗。
随着细节浮出水面，我们将进一步了解美国让步的程度和伊朗承诺的具体内容。
关键问题一目了然：
- 如果有的话，伊朗在其核计划方面做出了哪些切实承诺？
- 将会提供哪些制裁 relief？（注：此处“sanctions relief”为外交术语，标准译法为“制裁解除/豁免”，但结合语境译为“制裁减免”更符合中文外交表述习惯）
- 被冻结的伊朗资金是否会被解冻——以及何时解冻？
- 海峡是否会恢复到之前的状态，还是伊朗会通过收取费用来宣称掌控权？
- 美国就黎巴嫩问题向伊朗做出了哪些具体承诺？
这些答案将决定此次决策是合理的（基于BATNA的考量），还是一系列让步，可能为未来与一个虽被削弱但气焰更嚣张的伊斯兰共和国的战争埋下伏笔。
Iran agreement: Bad, BATNA or both?

- The Iran agreement may reflect concessions on sanctions and waterway management that the Trump administration previously ruled out.
- The concept of BATNA suggests President Donald Trump may have accepted an imperfect deal because the alternatives appeared worse than the available terms.
- Iran’s model in such negotiations depends on controlling leverage over assets and setting a price rather than seeking compromise.
AI-generated summary was reviewed by a CNN editor.
Brett McGurk is a CNN global affairs analyst who served in senior national security positions under Presidents George W. Bush, Barack Obama, Donald Trump and Joe Biden.
As the debate over a possible Iran agreement shifts from whether there will be a deal to what is in it, commentary is already racing ahead of the facts. We have not yet seen the text. We do not know the precise commitments, timelines or enforcement mechanisms — if any.
But based on what has emerged publicly, the administration appears to have conceded some positions it previously foreclosed — on sanctions and even long-term management of the Strait of Hormuz.
If so, many will conclude that President Donald Trump retreated on unfavorable terms.
Why might he have done so? It is worth considering a basic concept from negotiation theory: BATNA, or the best alternative to a negotiated agreement.
The question is simple: What happens if there is no deal? It’s one that diplomats ask when negotiations reach a decision-point.
Judging the agreement — and the alternatives
Last week, the talks appeared deadlocked. The decision was likely emerging as whether to walk away or to concede on some of Iran’s terms.
BATNA teaches that if walking away leaves you no worse off — or even strengthens your leverage for a future negotiation — then rejecting an unsatisfactory agreement may make sense. But if failure of talks leaves you in a worsening position, then even a flawed agreement becomes attractive.
That appears to be the debate Trump faced.
Those favoring an agreement likely pointed to mounting economic pressure from disruptions in Gulf shipping, rising energy prices, uncertainty in global markets, and the growing risk of military escalation. The alternatives to conceding on key terms were likely military escalation — and risk of Iran attacking Gulf infrastructure, worsening the economic pressure — or simply enduring the stand-off as energy demands began to peak and supplies tightened.
Those arguing against an agreement likely saw a different picture. Oil prices remained at manageable levels. A US-led maritime corridor through the strait was beginning to function. Iran’s economy was under increasing strain from sanctions and disruption to its oil exports. Time, in their view, was working against Tehran rather than Washington.
Trump appears to have accepted the former argument. If current reporting is accurate, he may have concluded that an imperfect deal was preferable to the alternatives before him.
And with Iran, there is another lesson that goes beyond BATNA.
I would take the “N” out entirely. Because there is often only one available deal.
I learned that lesson during negotiations for American hostages held by Tehran. In a hostage negotiation, Iran’s model is rarely based on compromise. It is based on possession. Tehran acquires something valuable, refuses to give it back, and then sets a price.
Meet the price and the hostage goes free. Refuse and the hostage remains captive. Iran knows it well.
The same logic appears to have shaped these negotiations.
Iran effectively gained leverage over one of the world’s most important waterways through threats to commercial shipping and energy flows. The central question was never whether Washington preferred Iran’s terms. The question was whether Washington was willing to pay the price required to reopen the strait.
Absent a viable alternative to a deal, the leverage in such a negotiation favored Iran.
As the details emerge, we’ll learn more about the extent of American concessions and Iranian commitments.
The key questions are straightforward:
- What real commitments — if any — has Iran made on its nuclear program?
- What sanctions relief is being granted?
- Will frozen Iranian money will be released — and when?
- Will the strait return to status quo ante, or is Iran asserting its control with fees?
- What precisely has been promised to Iran on Lebanon?
The answers will determine whether this was a defensible judgment call (the BATNA) or a series of concessions that may set the stage for a future war with a weakened — but emboldened — Islamic Republic.
