Here is what today looks like. The ceasefire, which was originally set to expire Tuesday evening Eastern time, will now expire Wednesday evening Eastern time — the deadline has slipped by roughly twenty-four hours, which is about the time it takes to fly from Washington to Islamabad. Vice President Vance is reportedly departing today for Wednesday’s talks. Iran has not confirmed attendance. The President has told reporters that this is Iran’s last chance to avoid destruction. All of this is described in the press as a development; readers of this blog will recognize most of it as a reprise.
When we last examined this situation, the question was whether the enrichment clause in the April 8 ceasefire could function as an agreement while being read in directly incompatible ways by the two domestic audiences it had to satisfy. The formal structure, extending Groseclose and McCarty’s “Politics of Blame,” is that when a negotiator bargains before two audiences simultaneously, the set of proposals both audiences can read favorably shrinks as their expectations diverge. The only clause available — if any clause exists — is whatever survives that intersection. When no such clause exists, you do not get an agreement. You get a document whose signatories can each tell their own audience they won.
What I want to do today is situate this moment in a longer arc. The mechanisms being enacted this week are mechanisms this blog has been describing for over a decade, and the recent Iran posts are the latest installments of a much older story.
Deadlines that move
In the Dispatches of March 20, I worked through the formal problem with a deadline that gets revised. Each revision updates the counterparty’s beliefs about the cost, to the threatener, of following through. The second revision carries less information than the first because its content is partly absorbed by the prior one. At the time, the subject was the serial extensions of the Strait of Hormuz deadline. A week later, the March 27 Dispatches noted that Iran had moved from the unconditional-closure option the ultimatum was built against to a toll regime, collecting rents denominated in yuan — a revelation about which future Iran expected to inhabit after the current conflict resolved. The deadline had become a data-generating process.
The ceasefire did not end that sequence. It interrupted it with a different kind of deadline — a two-week clock with an agreement that had to be reached, or not, before the clock ran out. The April 10 Dispatches described the threat-and-resolution compression that produced the ceasefire in the first place: a maximalist threat followed by a same-day agreement on terms that the two sides publicly characterized in incompatible ways. Today’s adjustment — moving the expiration from Tuesday to Wednesday — is one more revision on that same clock, and its informational content is partly absorbed by every revision that came before it. The counterparty now knows the shape of the threatener’s indifference curve a little more precisely than it did yesterday.
Showing up before the other side does
Vance is flying to Islamabad today. Iran has not confirmed that it is sending a delegation. This is an asymmetric signal. The side that commits first — commits travel, commits a principal, commits the press coverage that will follow if the other side fails to materialize — is doing something the other side is not. In a Schelling frame this is a coordination device. In a bargaining frame it is a partial commitment that restructures the expected outcome of the talks before the talks begin.
Thirteen years ago, in “Now, I’ll Show You Mine,” I argued that public and tangible concessions — going first with a specific proposal — can be a strong positive bargaining move even when they look like caves. Going public with a concrete proposal frames the next stage of the conversation and calls the counterparty’s bluff about whether they have a politically feasible alternative. The dual logic, from Boehner’s side of the 2012 fiscal cliff, appeared in “Make Me an Offer I Can’t Refuse (to Reject).” The decision to go first and the decision to refuse to go first operate under different logics, but neither is an unforced move. Each is a commitment in front of an audience.
The further wrinkle when going first happens in front of two domestic audiences is the subject of the April 17 post. It is also the subject of Scott Ainsworth’s 2015 guest post on Senator Cotton’s letter to the Iranian leadership, which examined the same two-audience structure in a different instantiation — an external audience being addressed explicitly, as if it needed instruction on domestic American constitutional arrangements, for the benefit of a domestic audience whose relationship to the external audience was being publicly re-drawn. That was eleven years ago. The cast has changed. The structure has not.
“Last chance” as a signaling problem
The President’s formulation is that this is the last opportunity for Iran to avoid destruction. That is a specific kind of threat: not a conditional to be enforced if violated, but a framing of the counterparty’s situation as a terminal node. The problem with terminal-node rhetoric is that it is only as persuasive as the speaker’s demonstrated willingness to follow through on prior, less terminal versions. When earlier deadlines have been moved, moved again, and moved a third time, each iteration of “last chance” carries less information than the one before.
This is the logic I worked through at length during the 2013 shutdown, in “Dis-Spence-ing with the Debt Debacle.” The post applied Spence to the sixteen-day impasse: costly inaction as a demonstration of ideological commitment, and the observation that when the real costs of continuing finally exceed the costs of capitulation, members of every conviction level pool at the same resolution. Three weeks ago, in “Paying the Hostage,” I revisited that mechanism in a new setting — the DHS shutdown, where the President’s unilateral memo paying TSA workers without congressional authorization introduced a third move the standard hostage-taking model does not contain. The pain, in that setting, was the material the signal was made of. When the pain is relieved without the concession, the signal does not complete.
“Last chance to avoid destruction” is a threat whose credibility depends on whether the speaker has, in the past, converted similar threats into the outcomes those threats described. The record is legible. It is legible to the Iranian leadership, and it is legible to every domestic constituency that will be reading Wednesday’s news.
A longer tail
For readers who have been here for a while, none of this is new territory. Foreign policy commitments as signaling problems appeared in “No War Left Behind?” and “Damn, He Asked US About Damascus,” both from the fall of 2013 during the congressional debate over Syria. Public opinion about military intervention, and how little it tracks information about the conflict, I took up in “My Ignorance Provokes Me” in 2014. The group-as-actor version of signaling that makes shutdowns work showed up in “Boehner in a Manger?” and the clean-CR posts of October 2013. The Iran arc of the last month — the March Dispatches, Monday’s “This Isn’t Cheap Talk,” the Kalshi week that threaded Iran through its examples, and the April 17 post — belongs to a longer sequence.
None of this makes today’s situation less serious. It means the mechanisms by which today’s situation will resolve — or fail to — are mechanisms we already have names for. The deadline that moves. The proposal that goes first. The threat whose credibility is depleted by the cost of its revision. The clause that can be read two ways because both audiences need it to be read two ways. Conservation of impossibility, in real time, on a clock.
What happens Wednesday evening will be described in the press as a development. Much of it will be legible, to readers of this blog, as a reprise.
With that, I leave you with this.
