US-Iran Talks Explained: Ceasefire, Hormuz and War Risk

The background

The United States and Israel began their war on Iran on February 28, and the conflict is now in its ninth month. Before the fighting started, Washington and Tehran were in indirect nuclear talks mediated by Oman. At talks in Geneva, Oman said both sides had made significant progress, and one day before the attacks began, Oman said Iran had agreed to reduce its nuclear stockpiles to the lowest level possible.

A memorandum signed between the US and Iran in June was supposed to steady things. Under it, Washington guaranteed oil waivers and said there would be no further restrictions on Iranian oil exports. When the memorandum collapsed months later, the US cancelled all the waivers. The closure of the Strait of Hormuz, the narrow waterway through which much of the world's oil moves, has since upended global energy markets.

The nuclear question runs underneath all of it. Iran is a signatory to the Nuclear Non-Proliferation Treaty, which it signed in July 1968 and ratified in February 1970. The treaty now has 191 parties, and it allows a country to withdraw with three months' notice if extraordinary events have jeopardised its supreme interests. The International Atomic Energy Agency has not had access to key Iranian nuclear facilities since the June 2025 war, which included attacks on the Fordow, Natanz and Isfahan sites.

Where things stand

On Saturday, October 31, Iran's Foreign Minister Abbas Araghchi told Al Jazeera that a US effort to open dialogue was "a positive step", but that Tehran saw no need to meet American officials at this stage. He said Iran had studied a letter sent by US Vice President JD Vance in high-level meetings. Qatari mediators were in Tehran on Friday, and an Iranian delegation has since travelled to Doha, where one of Araghchi's aides is continuing consultations.

Araghchi set out Tehran's conditions for reopening the Strait of Hormuz. Talks with the Qatari mediators shortened the implementation period of Iran's proposal to two days, he said, down from a Qatari suggestion of five days. The conditions include lifting sanctions imposed since the June memorandum collapsed, restoring oil waivers, releasing all frozen funds, including $6 billion held in Qatar, and reducing US forces in the region. Iran also wants recognition of shipping routes through the strait that it discussed with Oman, and the closure of other routes.

Tehran's other demands, reported by Iranian media, include lifting a US maritime blockade on Iranian ports and a truce for regional conflicts, including in Lebanon, where Israeli forces continue to occupy the south. Araghchi said mediators had presented proposals on the nuclear dossier, which Iran is reviewing as part of a second phase. Whether talks are direct or indirect, he said, depends on Tehran's conditions being met.

At the same time, Iran's warnings have hardened. Supreme Leader Mojtaba Khamenei met senior military commanders on Saturday and ordered maximum deterrence, including an immediate and effective response without geographical restriction if Iran is attacked again. Armed forces chief Major-General Ali Abdollahi said Iran would respond to any attack with immense force and would decide when any new war ends. Araghchi said Iran does not rule out an attack, and that its forces are at their highest level of readiness.

A separate pressure point opened in parliament on Saturday. Legislator Mahmoud Nabavian called for Iran to withdraw from the Nuclear Non-Proliferation Treaty and change its nuclear doctrine. Ebrahim Rezaei, a member of parliament's National Security and Foreign Policy Committee, said 10 proposals to withdraw had been registered. Iranian leaders have not yet responded to those demands, and the government's official position on not seeking nuclear arms remains unchanged, according to Al Jazeera's reporting.

The strait itself remains dangerous. The United Kingdom Maritime Trade Operations monitor reported 155 inbound and 122 outbound transits in the week ending October 28, which was 70 percent lower than pre-war levels. It reported a tanker approached by a small boat northeast of Oman's Khasab, with two explosive devices attached to the hull, causing a blast and fire in the engine room. Local authorities reported on Saturday afternoon that two fishing boats were bombed by a US drone south of Qeshm island in southern Iran, wounding several fishermen.

US Central Command chief Brad Cooper said in a video message on Friday that he had flown over the strait and seen dozens of vessels carrying crude oil and liquefied natural gas, supported by US aircraft and sea drones. He claimed Iran's Revolutionary Guard was not patrolling the waterway. That claim sits alongside [Iran's earlier warning to US warships to stay away as Trump weighs new strikes](/article/iran-warns-us-warships-stay-away-trump-weighs-new-strikes), which set out Tehran's military posture before this week's mediation.

What it means for the US

For American readers, this is not a distant standoff. The US military is already providing guidance and cover for a shuttle system moving oil from Arab states out of the strait, and US forces in the region are the explicit target of Tehran's retaliation warnings. Abdollahi said America and Israel would face an unimaginable response if Iran were attacked. A renewed war would also put US troops, ships and bases across the region in the firing line, not just targets inside Iran.

The nuclear terms in the Vance letter matter to the US as well. The letter is believed to have called for nuclear commitments from Iran, including allowing international inspectors to monitor its programme and settling the fate of its highly enriched uranium, which Tehran has said will not be shipped abroad. President Donald Trump has made "Iran cannot have a nuclear weapon" a non-negotiable condition for ending the conflict and securing a permanent deal.

Timing is tied to American politics too. Analysts cited by Al Jazeera expect the current standoff to hold until the November 3 midterm elections, and US media have reported that Washington warned Gulf allies to prepare for potential military action after that date. With [Democrats leading by 8 points as 43 million vote early in the midterms](/article/democrats-lead-8-points-43-million-vote-early-midterms), the election result could shape how much room Trump has to choose between a deal and a new round of strikes.

What to watch next

Three dates and decisions will tell which way this goes. First, Iranian sources told Al Jazeera a meeting to discuss a new diplomatic path could be held within a week, either in Doha or Istanbul. Second, Tehran is still studying the mediators' nuclear proposals, and its response, delivered through mediators rather than in a direct meeting so far, will show whether the Hormuz offer moves from words to action.

Third, watch parliament and the November 3 midterms together. If the withdrawal proposals in parliament gather formal support, the nuclear track gets harder, not easier. If the midterms pass without a deal, analysts warn the risk of renewed strikes rises sharply. An editorial in the Iranian state-linked Jomhouri-e Eslami newspaper put it plainly on Saturday: the chances of agreement look slim, fighting could break out after the elections, and war must not be accepted as the inescapable fate for Iran.
