Why the Iran ceasefire may have shifted the dynamics back in Trump's favor

Diplomacy between Washington and Tehran has not yet
unraveled, despite JD Vance’s theatrical departure from last week’s talks in
Islamabad. Trump now signals that the two sides could reconvene within days in
the Pakistani capital. Whether negotiators return to the table or continue
their exchanges through quieter, remote channels before the ceasefire lapses,
one reality appears to have shifted: Trump has clawed back a measure of
momentum—and with it, leverage—over Iran, largely by virtue of the ceasefire. Here’s
why.
Trump entered this moment politically cornered and
strategically constrained. Surging gasoline prices were inflicting acute
domestic pain, eroding his standing at home. More critically, he faced a barren
escalation ladder. Each conceivable move—strikes on Iran’s oil infrastructure,
attacks on civilian targets, the seizure of Persian Gulf islands, or covert
operations to capture enriched uranium—carried the near-certainty of forceful
Iranian retaliation. Such responses would not merely match his escalation but
compound it, deepening his economic exposure, amplifying political risk, and
entangling him further in a perilous and unwinnable strategic bind.
Nor could he simply extricate the United States from
the conflict on his own terms. Absent an understanding with Tehran, Iran
retained both the capacity and the incentive to continue targeting Israel and
vulnerable U.S. assets across the Gulf. Trump needed Iran’s permission
to get out of the war.
The ceasefire, however, has subtly altered that
equation. Trump may no longer need a formal nod from Tehran to step back. If he
disengages now—without a comprehensive agreement—Iran will almost certainly
maintain its grip over the Strait of Hormuz, a strategic setback for
Washington. Yet Tehran is unlikely to resume direct military operations against
U.S. targets in the Persian Gulf. To do so, in the absence of renewed American
strikes, would cast Iran as the aggressor, inviting severe and potentially coordinated
repercussions—not only from Washington but from wary global powers such as
Russia and China.
Moreover, the balance of needs has tilted. Iran now
appears to need an agreement more than the United States does. Trump has
already secured his central objective—the escape from a war he was ill-advised
to begin—while Iran, despite accruing leverage through its command of the
Strait, remains far from realizing its broader ambitions: meaningful sanctions
relief, a definitive and enduring end to hostilities, and perhaps even the
contours of a more stable, constructive relationship with Washington.
Tehran’s decision to dispatch its largest, most
senior, and most expansive delegation to Islamabad for direct talks with the
American vice president reflected a striking confidence—that it occupied its
strongest negotiating position vis-à-vis the United States since 1979. Yet to
convert that moment of perceived ascendancy into little more than a cessation
of U.S. bombardment would fall short of its aspirations. Even if Washington
were to acquiesce to Iran’s control of the Strait, such an outcome would pale against
the far more consequential gains Tehran believes are within reach.
Instead, Iran needs to translate this leverage not
only into a durable end to the war, but ideally, into a new peace:
One that delivers sweeping sanctions relief and inaugurates a more stable,
mutually defined economic and political relationship with Washington. Such an
arrangement would serve as a bulwark against renewed conflict. The economic
imperative is especially stark: sanctions relief is indispensable to
reconstruct a country now burdened with damage running into the hundreds of
billions of dollars.
As I have argued before, sanctions relief is not
merely an economic demand—it is a strategic necessity. Without it, Iran risks a
condition of chronic erosion, a slow but steady weakening that would leave it
exposed. That vulnerability, in turn, could invite further attacks. It was,
after all, the misperception of Iranian weakness that helped open the window
for initial strikes.
But Trump does not, in any fundamental sense, require
any of this. The United States can endure without a formal agreement with Iran
and without the benefits of an economic relationship with Tehran. To be sure, a
negotiated settlement would better serve long-term American interests: the
nuclear constraints Trump seeks can only be credibly secured at the negotiating
table. Abruptly abandoning diplomacy while leaving Iran in undisputed control
of the Strait would also unsettle key regional allies. Yet these are
strategic preferences, not immediate necessities.
Trump’s calculus is far more transactional and far
less patient. He can point to the damage already inflicted on Iran’s nuclear
infrastructure and conventional forces, proclaim a hollow victory, and
disengage. He has already emphasized that the United States no longer depends
on Persian Gulf oil, insulating it from the direct economic consequences of
Iran’s toll regime. As a result, the burden shifts outward: the Strait becomes
a problem for European and Asian powers—countries that Trump has noted declined
to rally to his side when he sought their help in prying the waterway from
Tehran’s grip.
The window now open offers Tehran a chance to convert
battlefield leverage into lasting strategic gain. To let it close would mean
forfeiting not just incremental progress, but the possibility of reshaping its
economic and geopolitical position. By contrast, the United States, having
already secured a tenuous exit ramp through the ceasefire, has less at stake in
the short term. Walking away, therefore, is politically and strategically
easier for Trump than for his Iranian counterparts. Both can live with diplomatic
failure, but Tehran has more gains to lose.
How Tehran chooses to navigate this narrowing
corridor—whether it presses its advantage or overplays its hand—will be
interesting to see.
