US-Iran tensions escalate: Peace talks or renewed war as Strait of Hormuz blockade intensifies

Are the US and Iran on the verge of a full peace agreement—or a return to all-out war? The answer remains unclear as conflicting signals emerge from both sides.

Conflicting Signals from Washington and Tehran

President Donald Trump has repeatedly told reporters that Iran has effectively agreed to all US conditions and that negotiations are progressing well. Vice President JD Vance is scheduled to travel to Pakistan this week to continue talks.

However, Iran’s recent actions paint a starkly different picture. After briefly reopening the Strait of Hormuz last week, Iran once again declared it closed over the weekend. Iranian forces fired on ships transiting the waterway, escalating tensions. The US, meanwhile, maintains a partial blockade on Iranian ports, seizing an Iranian vessel on Sunday.

There are doubts whether Iranian negotiators will even attend the meeting with Vance in Islamabad. The current impasse suggests a third possibility: the status quo may persist. Neither side appears willing to make concessions that could be perceived as humiliating, but the costs of this stalemate continue to rise daily.

The High Stakes of the Current Deadlock

The prolonged closure of the Strait of Hormuz and the looming threat of renewed war are taking a toll on both nations. The dynamic resembles the weeks of the US-Israeli bombing campaign, where the competition centered on endurance rather than decisive action.

In this new phase of the conflict, Iran holds the key to de-escalation. The question remains: Can the US and Iran reach a mutually acceptable agreement?

US Incentives vs. Iran’s Leverage

Currently, the US has strong incentives to end the war but lacks clarity on how to achieve this. Iran, on the other hand, has the means to end the conflict but appears hesitant to do so.

Before the war, the US sought to pressure Iran into abandoning its nuclear program entirely. Hawks in Washington also hoped for a broader deal that included Iran ending its support for proxy groups like Hezbollah in Lebanon and the Houthis in Yemen, as well as accepting limits on its ballistic missile program.

However, Trump’s recent statements to reporters notwithstanding, these broader goals have largely been abandoned. The current negotiations focus narrowly on Iran’s nuclear program and control of the Strait of Hormuz—issues that were not part of the initial conflict.

The Nuclear Program: A Double-Edged Sword

Ironically, Iran’s enrichment program may have done more harm than good. If Iran possessed an actual nuclear weapon today, it might have deterred some of the current aggression. Instead, its enrichment activities have drawn international scrutiny and military action.

Reports indicate that Iran was considering major concessions on its nuclear program even before the war began. These concessions included diluting its 400-kilogram stockpile of highly-enriched uranium. Yet, the path to peace remains uncertain as military actions continue to escalate on both sides.
