The most important U.S.-Iran talks in decades are now underway in Pakistan, but the diplomacy is happening under the shadow of fresh military pressure in the Strait of Hormuz, continued Israeli strikes in Lebanon, and deep disagreement over what a real end to the war would even look like.
Reuters reported Saturday that Vice President JD Vance, special envoy Steve Witkoff, and Jared Kushner met Iranian Parliamentary Speaker Mohammad Baqer Qalibaf and Foreign Minister Abbas Araqchi in Islamabad for roughly two hours. The talks were described as the highest-level U.S.-Iran contact in half a century. At almost the same moment, President Donald Trump said U.S. forces had begun “clearing out” the Strait of Hormuz and claimed 28 Iranian mine-dropping vessels had been sunk, a claim Iranian state-affiliated outlets quickly denied.
That is why this moment matters. The war may have slowed enough to create space for diplomacy, but nobody should confuse that with stability. The battlefield pressure is still there, the shipping crisis is still there, and the biggest political disputes between Washington and Tehran still look brutally unresolved.
What happened in Islamabad
According to Reuters, the U.S. and Iranian delegations met Saturday in Pakistan in what amounts to a historic diplomatic encounter. CNN, ABC News, and CBS News also reported that the high-stakes talks were underway, with no final agreement announced as of Saturday afternoon.
Pakistan has effectively turned its capital into a fortified negotiation zone. Reuters and BBC News described extraordinary security measures in Islamabad as the city hosted two governments that were trading major military blows only days ago. A Pakistani source told Reuters there were “mood swings” during the first round, with the temperature of the meeting rising and falling as both sides tested each other’s positions.
That alone tells you a lot. These are not trust-building talks. These are coercive talks, with both sides trying to shape the deal while keeping one hand on the trigger.
Trump’s Hormuz move raises the stakes
The clearest military headline Saturday was Trump’s claim that the United States had started clearing the Strait of Hormuz and had sunk 28 Iranian vessels involved in dropping mines. Reuters said Iranian state-affiliated Nournews called the report false, while Iranian state television said no U.S. ships had crossed the strait.
Even with those conflicting accounts, the strategic significance is obvious. Hormuz is not just another patch of water. Reuters noted that about 20% of global oil and liquefied natural gas shipments move through the chokepoint. Since the war erupted, traffic there has cratered. Reuters reported daily shipping volumes fell to less than 10% of their historical average after the start of the U.S.-Israel war.
There was one sign of movement. Reuters said three Liberian- and Chinese-flagged supertankers passed through the strait on Saturday, appearing to become the first vessels to exit the Gulf since last week’s ceasefire. That does not mean normal shipping is back. It means the waterway may be inching open just enough to test whether the ceasefire has any real weight behind it.
For Washington, reopening Hormuz is about more than optics. It is about proving that Iran cannot use one of the world’s most important energy corridors as a permanent bargaining chip. For Tehran, the strait has become its strongest piece of leverage. That is the heart of the current showdown.
The biggest gaps between Washington and Tehran
Reuters’ explainer on the Islamabad agenda laid out just how far apart the two sides remain. Iran wants sanctions relief, access to frozen assets, compensation for war damage, and recognition of its authority over the Strait of Hormuz, where it reportedly wants to collect transit fees and control access. Tehran also wants an end to fighting in Lebanon and insists that any durable settlement has to cover that front too.
The U.S. position is almost the mirror opposite. Washington wants free movement through Hormuz without tolls or restrictions. It also wants Iran’s nuclear program sharply constrained and its missile capabilities dramatically reduced. On uranium enrichment, Reuters said Trump has treated Iran’s demand to keep enriching as a non-starter.
That is why the talks are historically important but structurally fragile. The two sides are not haggling over minor language. They are fighting over the region’s military map, the global oil trade, the future of Iran’s deterrent, and the balance of power after six weeks of war.
Lebanon could still wreck the entire process
If Hormuz is the economic flashpoint, Lebanon is the military and political trapdoor under these talks.
Reuters reported that Israeli strikes in southern Lebanon continued Saturday and that Hezbollah said it had carried out several military operations against Israeli positions. Tehran wants a ceasefire in Lebanon folded into the broader diplomatic package. Israel and the United States have said the Lebanon campaign is not part of the Iran-U.S. ceasefire.
That disagreement is not some side issue. It may be the issue that decides whether this diplomatic track survives the weekend. Iran cannot easily sell a deal at home if Hezbollah remains under sustained Israeli attack. Israel, meanwhile, appears determined to keep pressure on Hezbollah regardless of what happens in Islamabad. If that front keeps burning, it could destroy the talks even if Washington and Tehran make progress elsewhere.
Why global markets are watching every word
The war has already hit far beyond the battlefield. Reuters said the conflict has killed thousands, jolted global oil prices, and slowed the broader economy. U.S. consumers have already felt the energy shock, and airlines and import-dependent businesses are watching the Strait of Hormuz like a heartbeat monitor.
That helps explain why so many governments are leaning in. Reuters reported that French President Emmanuel Macron spoke with Iranian President Masoud Pezeshkian and stressed the importance of de-escalation through the Pakistan talks. The issue is no longer just whether Washington and Tehran can step back from direct confrontation. It is whether they can do it before the energy disruption hardens into a wider economic crisis.
From a strategic perspective, Saturday’s talks are really about leverage. The United States still has overwhelming military reach, but Iran has shown it can impose global economic pain by choking shipping and tying negotiations to multiple fronts at once. That is a dangerous combination. It means even a weakened Iran can shape the terms of the crisis.
What happens next
No breakthrough had been confirmed by Saturday afternoon, and that probably should not surprise anyone. Reuters reported conflicting claims over whether Washington had agreed to release frozen Iranian assets, with an Iranian source saying yes and a U.S. official saying no. That kind of contradiction is exactly what negotiations look like when both sides are trying to control the narrative in real time.
Still, the fact that these talks happened at all is a major development. The U.S. and Iran have moved from threats and strikes to direct, senior-level contact in the middle of a live military crisis. That is real. So is the risk that the whole thing collapses just as fast.
The next 24 to 48 hours will matter more than the photo ops. If more tankers begin moving, if the Lebanon front cools, and if both sides stop publicly contradicting each other, then Islamabad could become the first real off-ramp of this war. If not, Saturday may be remembered less as the start of peace and more as a tense pause before the next round of escalation.
Right now, the situation looks exactly that fragile.
