Israel’s military said on Saturday it was preparing for the possibility of a lengthy war, while Iran’s foreign minister warned before the US attack that American military involvement “would be very, very dangerous for everyone”.
The prospect of a wider war threatened, too. Iranian-backed Houthi rebels in Yemen said they would resume attacks on US vessels in the Red Sea if the Trump administration joins Israel’s military campaign. The Houthis paused such attacks in May under a deal with the US
The US ambassador to Israel announced the US had begun “assisted departure flights”, the first from Israel since the Hamas-led attack on Oct 7, 2023, that sparked the war in Gaza.
But Trump appears to have made the calculation — at the prodding of Israeli officials and many Republican lawmakers — that Israel’s operation had softened the ground and presented a perhaps unparalleled opportunity to set back Iran’s nuclear programme, perhaps permanently.
The Israelis say their offensive has already crippled Iran’s air defences, allowing them to already significantly degrade multiple Iranian nuclear sites.
But to destroy the Fordo nuclear fuel enrichment plant, Israel has appealed to Trump for US bunker-busting bombs, the 30,000-pound GBU-57 Massive Ordnance Penetrator, which uses its weight and sheer kinetic force to reach deeply buried targets and then explode. The penetrator is currently only delivered by the B-2 stealth bomber, which is only found in the American arsenal.
The bomb carries a conventional warhead, and is believed to be able to penetrate about 200 feet (61m) below the surface before exploding, and the bombs can be dropped one after another, effectively drilling deeper and deeper with each successive blast.
The International Atomic Energy Agency has confirmed that Iran is producing highly enriched uranium at Fordo, raising the possibility that nuclear material could be released into the area if the GBU-57 A/B were used to hit the facility.
Previous Israeli strikes at another Iranian nuclear site, Natanz, on a centrifuge site have caused contamination only at the site itself, not the surrounding area, the IAEA has said.
Trump’s decision for direct US military intervention comes after his administration made an unsuccessful two-month push — including with high-level, direct negotiations with the Iranians — aimed at persuading Tehran to curb its nuclear program.
For months, Trump said he was dedicated to a diplomatic push to persuade Iran to give up its nuclear ambitions. And he twice — in April and again in late May — persuaded Israeli Prime Minister Benjamin Netanyahu to hold off on military action against Iran and give diplomacy more time.
The US in recent days has been shifting military aircraft and warships into and around the Middle East to protect Israel and US bases from Iranian attacks.
All the while, Trump has gone from publicly expressing hope that the moment could be a “second chance” for Iran to make a deal to delivering explicit threats on Khamenei and making calls for Tehran’s unconditional surrender.
“We know exactly where the so-called ‘Supreme Leader’ is hiding,” Trump said in a social media posting. “He is an easy target, but is safe there – We are not going to take him out (kill!), at least not for now.”
The military showdown with Iran comes seven years after Trump withdrew the US from the Obama-administration brokered agreement in 2018, calling it the “worst deal ever”.
The 2015 deal, signed by Iran, US and other world powers, created a long-term, comprehensive nuclear agreement that limited Tehran’s enrichment of uranium in exchange for the lifting of economic sanctions.
Trump decried the Obama-era deal for giving Iran too much in return for too little, because the agreement did not cover Iran’s non-nuclear malign behavior.
Trump has bristled at criticism from some of his MAGA faithful, including conservative pundit Tucker Carlson, who have suggested that further US involvement would be a betrayal to supporters who were drawn to his promise to end US involvement in expensive and endless wars.
