The cards they cannot play: Iran, America and the trap of unusable leverage
The strangest feature of the Iran war is not that both sides have leverage. It is that neither side can fully use the leverage it has.
That is the defining reality of the conflict as it moves through its uneasy post-ceasefire phase. Washington has the naval power to sustain pressure on Iran’s ports and shipping. Tehran has the geography to keep the Strait of Hormuz from returning to normal. Both instruments are real. Both hurt. Yet neither can be pushed to its logical end without creating costs that escape the control of the side using it.
The war has, therefore, entered a more dangerous stage than the familiar language of ceasefire suggests. The question is no longer simply whether Iran will reopen Hormuz or whether the United States will lift its blockade. It is whether either side can turn pressure into an outcome without being consumed by the pressure it has created.
That explains why the ceasefire has not become a settlement. It also explains why ships remain hesitant, markets remain unsettled and diplomacy keeps circling the same question: who moves first, and who loses most by doing so?
The blockade that delays the hard choice
The United States is not sustaining the blockade because it has found a clear path to victory. It is sustaining it because every alternative looks worse.

President Donald Trump has now reportedly told aides to prepare for an extended blockade of Iran after judging that renewed strikes or a clean withdrawal would carry greater risks. That calculation is understandable in narrow political terms. A renewed bombing campaign could push Iran towards wider retaliation against Gulf energy infrastructure. Walking away would make the war look like an unfinished act of force. Accepting Tehran’s proposal could allow Iran to recover its maritime position before Washington secures nuclear concessions.
So the blockade remains.
But pressure is not the same as strategy. A blockade can keep Iran under stress. It can reduce export options, complicate oil sales and force Tehran to spend political capital on relief. What it cannot do, by itself, is guarantee the political result Washington wants.

If Iran does not capitulate, the blockade........
