Diplomatic efforts to secure a highly anticipated ceasefire between the United States and Iran hit a severe bottleneck on Tuesday following a reported confrontation between US President Donald Trump and Israeli Prime Minister Benjamin Netanyahu.

The friction comes even as Tehran continues reviewing a draft memorandum of understanding (MOU) aimed at reopening the strategic Strait of Hormuz.

Heated Exchange Over Air Strikes

According to reports carried by Axios, a furious phone conversation took place between President Trump and Prime Minister Netanyahu after recent Israeli military operations deep inside Lebanese territory threatened to destabilise delicate, ongoing backchannel diplomacy between Washington and Tehran.

Sources familiar with the matter indicated that Trump used strong language, questioning the timing of the strikes and reminding the Israeli premier of past political backing from Washington.

The diplomatic fallout was immediate. Hours after the report emerged, Iranian state media indicated that Tehran was maintaining a highly cautious posture regarding the proposed text.

Tehran Reviews Draft Pact

The semi-official Mehr News Agency, quoting an informed source close to Iran's negotiating team, stated that the Islamic Republic is meticulously evaluating the final text of the potential MOU with the United States.

The source noted that Washington’s historical record of "breaking commitments" has forced Iranian draft reviewers to adopt an exceptionally strict approach before sending a formal response.

Despite the friction, President Trump expressed optimism during a subsequent media interaction, stating he still anticipates a formal agreement within the week to extend the current ceasefire framework and restore maritime traffic through the Strait of Hormuz.

Lebanon Escalation Threatens Dialogue

The ground reality in southern Lebanon, however, remains highly volatile. Overnight, Israeli forces conducted extensive air strikes and artillery shelling across Nabatieh, Tyre, and several smaller villages including al-Mansouri and Jibshit. Local authorities confirmed multiple casualties, including a civilian vehicle targeted on the Nabatieh-Khardali road.

The continued military offensive drew a sharp response from Iranian Parliament Speaker and chief negotiator Mohammad Bagher Ghalibaf. Following a phone call with Lebanese Parliament Speaker Nabih Berri, Ghalibaf warned via social media that continued operations by Israeli forces would lead to a total suspension of the dialogue process with Washington.

Global Markets Feel Pressure

The protracted conflict continues to trigger economic adjustments worldwide. Fresh data revealed that the United States has drawn down its Strategic Petroleum Reserve (SPR) to 357.1 million barrels—its lowest level since early 2024—in an effort to stabilise global energy supplies.

Simultaneously, international agricultural sectors are tracking supply chain shifts, with Australian authorities cutting their annual wheat harvest outlook due to rising fertilizer and diesel costs linked to the prolonged closure of shipping lanes.

Uncertain Next Steps Ahead

While international mediators, including France, have called for an immediate cessation of hostilities and questioned the justification for extended military presence in southern Lebanon, the next 48 hours remain critical.

Diplomatic sources suggest that the final execution of the US-Iran MOU hinges entirely on stabilizing the Israel-Hezbollah front, which has seen repeated projectile interceptions and drone activity despite a preliminary nod to a US-backed peace proposal.

West Asia War De-escalation Talks Begin In Islamabad Today

71-member Iranian delegation arrives for high-stakes negotiations with the US

A high-powered 71-member Iranian delegation touched down in the Pakistani capital on Saturday morning, setting the stage for critical de-escalation talks with the United States as the West Asia war enters its 43rd day.

Diplomatic Heavyweights Arrive

The Iranian team is led by Parliament Speaker Mohammad Bagher Ghalibaf. The delegation includes Foreign Minister Abbas Araghchi, a former senior commander of the Islamic Revolutionary Guard Corps (IRGC), and the central bank governor. US Vice President JD Vance is also expected in Islamabad later today. The formal negotiations between all stakeholders are scheduled for Saturday.

Empty Seats as Tribute

In a deeply symbolic gesture, the Iranian delegation kept several seats on their aircraft empty. Officials confirmed this was a tribute to the victims of the Minab Elementary School tragedy. A missile strike on the Shajareh Tayyebeh girls’ school in southern Iran on March 28 killed at least 175 people, most of them children aged between seven and 12.

Iran’s Firm Pre-Conditions

Sources indicated that Tehran has drawn a clear red line before talks begin. Iran insists it will not hold direct discussions with the US until two conditions are met. First, a complete ceasefire must be implemented in Lebanon. Second, Iran’s frozen billions of dollars in international banks must be released. This stance comes as the UN reports that up to 1.2 million people have fled their homes in Lebanon due to Israeli strikes.

Pakistan’s Brokering Role

For Pakistan, hosting the talks is a moment of significant diplomatic prestige. Digital billboards reading "Islamabad Talks" now line the capital’s streets, displaying the flags of the US, Iran, and Pakistan. The government has declared a two-day public holiday to mark its role in brokering the two-week ceasefire that preceded these negotiations. According to a BBC analysis, Islamabad is actively celebrating its position as a peace broker between the two rival nations.

Key Issues on the Table

The core of the negotiations revolves around Iran’s nuclear and ballistic missile programs. The US is demanding that Tehran phase out all high-level enriched uranium and place verifiable limits on its nuclear facilities. Washington also wants a complete ban on Iran’s long-range ballistic missiles. In return, Tehran is demanding the immediate lifting of all international sanctions and compensation for frozen assets.

Global Impact and Outlook

Oil markets have already reacted to the possibility of peace. US crude prices fell by over 13% this week, dropping from nearly $111 to $96.57 per barrel—the largest weekly decline since the war began. While a White House televised address on the ceasefire was reportedly considered and then set aside, officials remain cautiously optimistic. As one source put it, ensuring Iran does not possess nuclear weapons remains “99% of the deal” from the American perspective. The world now watches Islamabad to see if the remaining 1% can be bridged.
