Who are Iran's true allies and will they help if US joins the war?
As Israel continues its attacks on Iran, US President Donald Trump and other global leaders are hardening their stance against the Islamic Republic.
While considering a US attack on Iran's nuclear sites, Trump has threatened Iran's supreme leader, claiming to know his location and calling him 'an easy target.' He has demanded 'unconditional surrender' from Iran.
Meanwhile, countries such as Germany, Canada, the UK and Australia have toughened their rhetoric, demanding Iran fully abandon its nuclear program. So, as the pressure mounts on Iran, has it been left to fight alone? Or does it have allies that could come to its aid?
Has Iran's 'axis of resistance' fully collapsed?
Iran has long relied on a network of allied paramilitary groups across the Middle East as part of its deterrence strategy. This approach has largely shielded it from direct military strikes by the US or Israel, despite constant threats and pressure.
This so-called 'axis of resistance' includes groups such as Hezbollah in Lebanon, the Popular Mobilization Forces (PMF) in Iraq, the Houthi militants in Yemen, as well as Hamas in Gaza, which has long been under Iran's influence to varying degrees. Iran also supported Bashar al-Assad's regime in Syria before it was toppled last year.

These groups have served both as a regional buffer and as a means for Iran to project power without direct engagement. However, over the past two years, Israel has dealt significant blows to the network.
Hezbollah — once Iran's most powerful non-state ally — has been effectively neutralised after months of attacks by Israel. Its weapons stocks were systematically targeted and destroyed across Lebanon. And the group suffered a major psychological and strategic loss with the assassination of its most influential leader, Hassan Nasrallah.
In Syria, Iranian-backed militias have been largely expelled following the fall of Assad's regime, stripping Iran of another key foothold in the region.
That said, Iran maintains strong influence in Iraq and Yemen. The PMF in Iraq, with an estimated 200,000 fighters, remains formidable. The Houthis have similarly-sized contingent of fighters in Yemen.
Should the situation escalate into an existential threat to Iran — as the region's only Shiite-led state — religious solidarity could drive these groups to become actively involved. This would rapidly expand the war across the region.
The PMF, for instance, could launch attacks on the 2,500 US troops stationed in Iraq. Indeed, the head of Kata'ib Hezbollah, one of the PMF's more hardline factions, promised to do so:
If America dares to intervene in the war, we will directly target its interests and military bases spread across the region without hesitation.
Iran itself could also target US bases in the Persian Gulf countries with ballistic missiles, as well as close the Strait of Hormuz, through which about 20% of the world's oil supply flows.

Will Iran's regional and global allies step in?
Several regional powers maintain close ties with Iran. The most notable among them is Pakistan — the only Islamic country with a nuclear arsenal.
For weeks, Iranian Supreme Leader Ali Khamenei has tried to align Iran more closely with Pakistan in countering Israel's actions in Gaza.
In a sign of Pakistan's importance in the Israel-Iran war, Trump has met with the country's army chief in Washington as he weighs a possible strike on its neighbour.
Pakistan's leaders have also made their allegiances very clear. Prime Minister Shehbaz Sharif has offered Iran's president 'unwavering solidarity' in the 'face of Israel's unprovoked aggression.' And Pakistani Defence Minister Khawaja Asif recently said in an interview Israel will 'think many times before taking on Pakistan.'
These statements signal a firm stance without explicitly committing to intervention.
Yet, Pakistan has also been working to de-escalate tensions. It has urged other Muslim-majority nations and its strategic partner, China, to intervene diplomatically before the violence spirals into a broader regional war.
In recent years, Iran has also made diplomatic overtures to former regional rivals, such as Saudi Arabia and Egypt, in order to improve relations.
These shifts have helped rally broader regional support for Iran. Nearly two dozen Muslim-majority countries — including some that maintain diplomatic relations with Israel — have jointly condemned Israel's actions and urged de-escalation.
It's unlikely, though, that regional powers such as Saudi Arabia, Egypt, the United Arab Emirates and Turkey would support Iran materially, given their strong alliances with the US.
Iran's key global allies, Russia and China, have also condemned Israel's strikes. They have previously shielded Tehran from punitive resolutions at the UN Security Council.
However, neither power appears willing — at least for now — to escalate the confrontation by providing direct military support to Iran or engaging in a standoff with Israel and the US.
Theoretically, this could change if the conflict widens and Washington openly pursues a regime change strategy in Tehran. Both nations have major geopolitical and security interests in Iran's stability.
This is due to Iran's long-standing 'Look East' policy and the impact its instability could have on the region and the global economy. However, at the current stage, many analysts believe both are unlikely to get involved directly.
Moscow stayed on the sidelines when Assad's regime collapsed in Syria, one of Russia's closest allies in the region. Not only is it focused on its war in Ukraine, Russia also wouldn't want to endanger improving ties with the Trump administration.
China has offered Iran strong rhetorical support, but history suggests it has little interest in getting directly involved in Middle Eastern conflicts.

Iran warns of retaliation as Israeli attacks continue
Iran warns of retaliation as Israeli attacks continue Iran's President Masoud Pezeshkian said Iran would not halt its nuclear programme "under any circumstances". File photo: AFP Iran's President Masoud Pezeshkian warned Saturday of a "more devastating" retaliation should Israel's nine-day bombing campaign continue, saying the Islamic republic would not halt its nuclear programme "under any circumstances". Israel said on Saturday it had killed three more Iranian commanders in its unprecedented offensive, and Foreign Minister Gideon Saar claimed Tehran's alleged progress towards a nuclear weapon had been set back by two years. "We will do everything that we can do there in order to remove this threat," Saar told the German newspaper Bild, adding that Israel would keep up its onslaught. Israel and Iran have traded wave after wave of devastating strikes since Israel launched its aerial campaign on June 13, saying Tehran was on the verge of developing a nuclear weapon. On Saturday, Israel said it had attacked Iran's Isfahan nuclear site for a second time, with the UN nuclear watchdog reporting that a centrifuge manufacturing workshop had been hit. Later Saturday Iran's Mehr news agency said Israel had launched strikes on the southern city of Shiraz, which hosts military bases. And early Sunday, Iran's Revolutionary Guard announced that a "vast" wave of "suicide drones" had been launched against "strategic targets" across Israel. Iran denies seeking an atomic bomb, and on Saturday Pezeshkian said its right to pursue a civilian nuclear programme "cannot be taken away... by threats or war". (AFP)

US B-2 bombers moving to Guam amid Israel-Iran tensions
The United States is moving B-2 bombers to the Pacific island of Guam, two US officials said on Saturday, as US President Donald Trump weighs whether the United States should take part in Israel's strikes against Iran. It was unclear whether the bomber deployment is tied to Middle East tensions. Speculation about a potential US strike has focused on the B-2s, which would be needed to drop 30,000-pound (1,360kg) GBU-57 Massive Ordnance Penetrators – so-called 'bunker busters' – if Trump decided to target Iran's heavily fortified underground uranium enrichment site at Fordow. Israel, which is seeking to destroy Iran's nuclear capabilities, does not have such weapons. The officials, speaking on the condition of anonymity, declined to disclose any further details. One official said no forward orders had been given yet to move the bombers beyond Guam. They did not say how many B-2 bombers were being moved. 04:26 Trump says US 'may' or 'may not' strike Iran as Tehran rejects call to surrender Trump says US 'may' or 'may not' strike Iran as Tehran rejects call to surrender The Pentagon did not immediately respond to a request for comment.

Iran: Over 400 killed since start of war with Israel
Iran: Over 400 killed since start of war with Israel Tehran says Israeli attacks have also left 3,056 others wounded. File photo: Reuters Israeli strikes on Iran have killed more than 400 people since they began last week, the Islamic republic's health ministry said in an updated toll on Saturday. "As of this morning, Israeli attacks have claimed the lives of over 400 defenceless Iranians and left 3,056 others wounded by missiles and drones," health ministry spokesman Hossein Kermanpour said in a post on X. Several "powerful explosions" were heard in the afternoon in southwestern Iran's Ahvaz, the daily Shargh reported, as Israel's military said it was conducting strikes on "military infrastructure" in the area. Ahvaz is the capital of Khuzestan province, which lies on the Iraqi border and is Iran's main oil-producing region. "Fighter jets are currently striking military infrastructure in southwestern Iran," the Israeli military said in a statement. The country's military also said it had killed a top Iranian official in charge of military coordination with the Palestinian militant group Hamas, as well as two other Iranian commanders overnight. Earlier, Israeli rescue services said an Iranian "drone strike hit a two-storey residential building in northern Israel" following a wave of attacks reported by the military. Meanwhile, Iran's Foreign Minister Abbas Araghchi arrived in Istanbul for a meeting with regional diplomats to discuss Tehran's conflict with Israel. Around 40 diplomats are due to join the weekend gathering of the Organisation of Islamic Cooperation, as Israel and Iran continue to exchange attacks. (AFP)
