The Siege That Picks a Side

by Patrick Jaritz / VICTOR

A naval blockade is a blunt object, and it does not choose a target inside the government it squeezes. Yet the siege Washington restarts against Iran this week did exactly that the last time it ran, and the faction it strengthened is the one now left holding a failed deal. The blockade produced June's ceasefire by empowering Iran's president over a reluctant supreme leader. That deal has collapsed, the president owns the loss and the same pressure now arms the camp that always wanted the fight. The United States is reaching for the tool that worked in June. It is applying that tool to a very different room.

On July 14 the United States switches the blockade of Iran's ports back on. The ceasefire that held since mid-June has come apart, the Strait of Hormuz is under fire again, and Washington has returned to the instrument credited with ending the previous round. The logic looks simple. The blockade produced a deal once. Run it again, get another deal.

That logic holds only if the blockade squeezes Iran as a single body. The record from the spring says it squeezed through one man. Iran's president spent those months frightened by the siege and a sinking economy, and he carried that fear into the supreme leader's office and argued for the June agreement over the leader's own reluctance to surrender the strait. The supreme leader agreed on a single condition. The president would own the outcome if the deal fell apart.

That condition is now the whole story. The deal has fallen apart. The president who staked himself on it holds the loss, by the exact terms he accepted. And the pressure that once loaded his side of the internal argument has returned at the worst possible moment for him. The camp that never wanted the agreement can point at the reviving blockade and make its case in two sentences. Concession bought a renewed siege. Talking to Washington was the error.

A blockade that bites the economy is one thing. A blockade that bites the standing of the man who bet on diplomacy is another, and the second is what is arriving. The siege keeps its economic force. The oil revenue that briefly returned during the ceasefire goes away again, and it goes away for a regime that told its own people the war was finished. What has shifted is where that force lands. In the spring it strengthened the argument for a deal. This week it strengthens the argument for the fight.

None of this makes the blockade useless. A long enough siege against a deep enough collapse can break any calculation, and the pragmatic camp could recover its footing as the privation deepens. The bounded claim is narrower and firmer. Right now the instrument the United States is reusing produced its result by empowering a faction that the result then destroyed. The tool has not changed. The board it plays on has.

One caution belongs in plain sight. The internal picture rests on a thin base, a single detailed account of what passed between the president and the supreme leader in June. The strikes and the shipping collapse and the failed mediation are visible from many angles. The palace argument is visible from one. This reading follows the best available account of how the last concession was won, and a second independent source could still redraw it.

For now the shape holds. Washington is running its winning move into a room that has rearranged the furniture against it.
