Has WWIII started and how close has Iran come to having a nuclear bomb?

Has WWIII started and how close has Iran come to having a nuclear bomb?

Metro4 hours ago

After Donald Trump's decision to dramatically intervene in the conflict between Israel and Iran, many urgent questions are being asked.
Does Israel have nuclear weapons – and how many? And could the conflict trigger a wider war, even World War III? Has it started already?
As Iran mulls whether to retaliate against the US after three key nuclear sites were bombed, understanding what is at stake is more important than ever.
This is what we know about Israel's nuclear arsenal, and whether the current crisis could spiral into a much larger war.
Israel's military superiority in the Middle East comes not just through its conventional arsenal or the backing of the US – but from its rich nuclear arsenal.
It is one of nine countries to possess such nukes, and the only one in the region – and it is widely believed to have one of the most advanced such programmes in the world.
Despite widespread acknowledgement by experts and former government officials of their existence, Israel has never confirmed this.
Since the 1960s, it has followed a policy of nuclear ambiguity. At the time, it went to great lengths hide its nuclear ambitions from the international community, even its closest allies.
Even US inspectors were misled during early visits to the Nuclear Research Center near Dimona, in the Negev desert, which was initially described as a textile factory.
Today, estimates of its stockpile range between 90 and 400 warheads, all of which could be delivered by air, as cruise missiles fired from submarines and through the Jericho line of ballistic missiles.
A few days before Israel's unprecedented attack on Iran, in which dozens of people – most of them civilians – have been killed, Iran had threatened to release a hoard of Israeli nuclear secrets it claims to have obtained.
Last Sunday, Iran's intelligence minister, Esmail Khatib, claimed the regime had obtained 'a vast collection of strategic and sensitive documents, including plans and data on the nuclear facilities'.
Iran is transparent about having a nuclear programme but insists that it has developed no warheads.
But ever since the US pulled out of a landmark nuclear non-proliferation treaty in 2018 under Donald Trump, it has been ramping up production of fissile material in recent years.
Iran now enriches uranium to near weapons-grade levels of 60%, the only country in the world without a nuclear weapons programme to do so.
Under the original 2015 nuclear deal, Iran was allowed to enrich uranium up to 3.67% purity and to maintain a uranium stockpile of 300 kilograms.
During his second term in the Oval Office, Trump has been working to reach an agreement on curbing Iran's programme.
There have been several rounds of talks between the US and Iran – up until the Israeli attacks – and Trump imposed new sanctions on the country as part of his 'maximum pressure' campaign.
A nuclear bomb isn't something you can just build overnight – it comes down to uranium enrichment.
Uranium contains a radioactive isotope, called U-235, that can be used as a power source. The more refined it is – enriched – the more powerful it is, which can be achieved by spinning it around in a centrifuge.
Nuclear power plants only need relatively unenriched uranium at 0.7% to 5%, while weapons-grade nuclear weapons need 90%.
The International Atomic Energy Agency says Iran has about 400kg worth of uranium enriched to 60%. At 90% enrichment, this is enough for 10 warheads.
Iran Watch warns that the country could enrich enough uranium for one weapon in four months, and five in one year and eight months. Though, Iran would also need to build a warhead and a missile capable of delivering it.
If the US claims about the extent of damage at the three nuclear sites prove correct, these efforts will likely have taken a massive hit.
The US launched strikes early this morning against three nuclear sites in Fordow, Isfahan and Natanz.

President Donald Trump announced from the White House: 'Iran's key nuclear enrichment facilities have been completely and totally obliterated.'
Trump has said Iran cannot be allowed to develop nuclear weapons which could be used to attack Israel or other targets in the West.
Sir Keir Starmer backed the strikes, describing the nuclear programme as 'a grave threat to international security'.
Even after the involvement of the US, it is unlikely that it will result in a global conflict. More Trending
Jason Pack, fellow at Royal United Services Institute (RUSI) and host of the Disorder Podcast, told Metro that the Iranian regime is 'really weakened'.
He said: 'The Iranians don't have the capability to bring us to World War III.
'It is much more likely to see the Iranian people rise up against the regime than we are to see the Iranians like land some decisive blow against Israel.'

Plaid to PM: 'Don't follow Trump into Middle East conflict'

Rhun ap Iorwerth, MS for Ynys Môn, and Liz Saville Roberts, MP for Dwyfor Meirionnydd, welcomed Prime Minister Keir Starmer's calls for diplomacy and de-escalation, but voiced concerns that he had fallen short of roundly condemning President Trump's authorisation of US strikes against Iran overnight. The Plaid Cymru politicians said that the pursuit of peace should take priority over any UK loyalty to the US and warned against repeating history where the UK entered a regional conflict in the Middle East as 'America's puppet.' In a joint statement, Mr ap Iorwerth and Ms Saville Roberts said: 'President Trump's decision to launch US strikes against Iran is potentially catastrophic for an already destabilised region. 'Whilst Prime Minister Keir Starmer's calls for diplomacy and de-escalation are to be welcomed, it is concerning that he has fallen short of roundly condemning President Trump's actions. 'The pursuit of peace should take priority over any UK loyalty to the US. We all remember the disastrous consequences of being dragged into a regional conflict in the Middle East as America's puppet. 'It is essential therefore that Parliament has the opportunity to veto any UK military involvement in the Israel-Iran conflict should Keir Starmer yield to any pressure from President Trump and propose some form of intervention. 'In the same way the US Democrats are divided on the issue, Keir Starmer may well face pressure from Labour hawks to follow President Trump's lead. 'Air strikes were launched against Syria in 2018 without granting Parliament an opportunity to vote on military action. At the time Plaid Cymru accused then-Prime Minister Theresa May of showing complete disregard towards democracy. 'We stand firmly by that view and reiterate our calls for restraint before more innocent civilian lives are lost.' The US strike on Iran has fuelled fears that Israel's war with Tehran could escalate to a wider regional conflict. World leaders have reacted with calls for diplomacy and words of caution. US President Donald Trump had said on Thursday that he would decide within two weeks whether to get involved. In the end, it took just days, and Washington inserted itself into Israel's campaign with its early attack early on Sunday, reports the Press Association (PA).

Remains of three Israeli hostages recovered from Gaza

The military identified the remains as those of Yonatan Samerano, 21; Ofra Keidar, 70; and Shay Levinson, 19. All three were killed during Hamas's October 7, 2023, attack into Israel that ignited the ongoing war. The militant group is still holding 50 hostages, with less than half of them believed to be alive. The military did not provide any details about the recovery operation, and it is unclear if an air strike which killed four Palestinians was related to it. 'The campaign to return the hostages continues consistently and is happening alongside the campaign against Iran,' Prime Minister Benjamin Netanyahu said in a statement. Kobi Samerano said in a Facebook post that his son's remains were returned on what would have been Yonatan's 23rd birthday. Hamas-led militants killed some 1,200 people, mostly civilians, and abducted 251 people in the October 7 attack. More than half the hostages have been returned in ceasefire agreements or other deals, eight have been rescued alive and Israeli forces have recovered dozens of bodies. Israel's retaliatory offensive has killed more than 55,000 Palestinians, according to Gaza's Health Ministry, which has said women and children make up more than half of the dead. It does not distinguish between civilians and combatants. Four people were killed on Sunday in an air strike in the built-up Nuseirat refugee camp in central Gaza, according to Al-Awda Hospital, where the bodies were brought. It said another 22 people were injured while waiting for aid trucks. Palestinian witnesses and health officials say Israeli forces have repeatedly opened fire on crowds seeking desperately needed food, killing hundreds of people in recent weeks. The military says it has fired warning shots at people it said approached its forces in a suspicious manner. The Hostages Families Forum, the main organization representing families of the hostages, has repeatedly called for a deal to release the remaining captives. 'Particularly against the backdrop of current military developments and the significant achievements in Iran, we want to emphasise that bringing back the remaining 50 hostages is the key to achieving any sort of victory,' it said in a statement on Sunday. Hamas has said it will only release the remaining hostages in return for more Palestinian prisoners, a lasting ceasefire and an Israeli withdrawal from Gaza. Mr Netanyahu has rejected those terms, saying Israel will continue the war until all the hostages are returned and Hamas is defeated or disarmed and sent into exile. Even then, he has said Israel will maintain lasting control over Gaza and facilitate what he refers to as the voluntary emigration of much of its population, plans the Palestinians and others view as forcible expulsion. Separately, World Central Kitchen, the charity run by celebrity chef Jose Andres, said it had resumed the distribution of hot meals in Gaza for the first time in six weeks after shutting down because of Israel's blockade, which was loosened last month amid fears of famine.

Starmer urges Britons to contact Foreign Office for Israel evacuation flights

It comes after the US attacked three nuclear sites in Iran overnight and Tehran then launched a ballistic missile barrage against Israel. Speaking to Sky News, Sir Keir Starmer said: 'I urge all citizens to make contact with the Foreign Office so that we can facilitate whatever support is needed.' He added that the Government will help evacuate British citizens on charter flights 'as soon as we can'. Sir Keir said: 'Well for British citizens, we've been saying for some time to register their presence. 'And so far as Israel is concerned, just as soon as we can get charter flights off, we will do so.' The UK is preparing a flight to transport vulnerable British nationals and their dependants out of Israel and the OPTs early next week. British nationals in Israel and the OPTs should register their presence to receive the latest updates and register their interest in the… — Foreign, Commonwealth & Development Office (@FCDOGovUK) June 22, 2025 The Foreign, Commonwealth and Development Office (FCDO) has continued to urge British nationals to register their details and interest in evacuation flights, the first of which it said will take off early next week. It said further flights 'will be considered depending on demand and the latest security situation'. According to the Israeli Government, some 22,000 tourists are seeking to board evacuation flights. It is unclear how many of these are UK citizens. British nationals who have already registered will automatically be contacted and provided with a link to the booking portal, the FCDO said. Those eligible for the flight will be expected to pay for their seat – and payment will be taken on registration on the flight booking form. The FCDO added that those with 'greatest need' will be prioritised, and British nationals plus their non-British immediate family members travelling with them are eligible. All passengers must hold a valid travel document, and those non-British immediate family members will require valid visas/permission to enter or remain that was granted for more than six months, the FCDO said. The UK has been working on charter flights for Britons in Israel but none have so far taken off as the country's airspace has been closed. Business Secretary Jonathon Reynolds told Sky News on Sunday morning: 'We are in active conversations about chartering aircraft to get people out.' Asked if that will happen imminently, Mr Reynolds said: 'I believe our intention would be to do that as soon as possible… hours, not days.' Meanwhile, shadow foreign secretary Dame Priti Patel told Times Radio the UK 'must not be behind the curve' in evacuating its nationals. 'The Government's got to start moving fast now in terms of British nationals in Israel,' Dame Priti said. 'They've been talking about this for days… Israeli airspace is shut down. 'The Americans are ready to evacuate 25,000 US nationals — we must not be behind the curve.' The FCDO has warned British nationals not to make their way to the airport unless they are contacted. Register your presence: — Foreign, Commonwealth & Development Office (@FCDOGovUK) June 22, 2025 A spokesperson said: 'This is a perilous and volatile moment for the Middle East. 'The safety of British nationals in Israel and the Occupied Palestinian Territories continues to be our utmost priority – that's why the UK Government is preparing flights to help those wanting to leave. 'Working closely with the Israeli authorities, our staff are continuing to work at pace to assist British nationals on the ground and ensure they receive the support they need.' Commercial flights remain in operation from Egypt and Jordan to the UK, and international land border crossings to these countries remain open. The FCDO said the situation 'remains volatile' and the Government's ability to run flights out of Israel and the Occupied Palestinian Territories 'could change at short notice'. The portal to register presence in Israel as a Briton is available at:
