US–Israel–Iran war day three: aims, IRGC, outcomes

It is only day three and the fighting already stretches across borders. Iran has struck Arab states aligned with Washington as well as neighbours across the Gulf. In London, the UK has dropped its earlier refusal to let the US use its bases. And in a sign of how fast this is moving, US Central Command said three US F‑15E Strike Eagles were downed by Kuwaiti air defences in an apparent friendly‑fire incident. In moments like this, it helps to pause and map what each side wants, who holds power inside Iran, and the ways wars like this have ended before.

Start with Washington. In a video message filmed in Florida, President Trump set out a checklist: erase Iran’s missile industry, neutralise its navy, and stop Tehran’s allied militias from striking Americans and destabilising the region. He also urged Iranians to ‘take over’ once the shooting stops. Alongside the rhetoric sit claims that Iran can soon build missiles to reach the US and is close to a nuclear weapon; current US intelligence does not publicly say that, and the President has previously boasted that US action ‘obliterated’ Iran’s nuclear sites. For our purposes, notice the gap that can open up between stated goals, available evidence, and timelines.

For Israel, Prime Minister Benjamin Netanyahu has for decades treated Iran as the main strategic threat. If mass protests cannot overturn the system, his near‑term aim is to smash Iran’s ability to rebuild and arm proxy forces that can threaten Israel. There is a domestic clock too. With elections due later this year, a decisive blow against Iran would go a long way towards repairing the damage to his standing since Hamas’s 7 October 2023 attacks.

Tehran’s objective is simpler to describe: survival. Since 1979 the Islamic Republic has been engineered to withstand assassinations and wars. Its overlapping religious and political institutions are designed to keep the state running even if leaders fall. That does not guarantee success now, but it explains why the system can look battered yet still coherent.

To understand how it holds, we need to know who’s who. The Islamic Revolutionary Guard Corps (IRGC) exists to defend the revolution at home and abroad. Estimates often cite roughly 190,000 active personnel and as many as 600,000 reservists. Beyond doctrine, the IRGC also controls a large slice of the economy, giving commanders financial as well as ideological reasons to stay loyal when the stakes rise.

Then there is the Basij, a volunteer paramilitary force of perhaps 450,000. In past crackdowns, including the 2009 protests, they acted as the first line-on foot with batons or on motorbikes as fast‑moving squads. In practice, the Basij can flood streets quickly, with the IRGC and heavily armed police layered behind them. For citizens, that depth of force can make organised dissent extremely risky.

Threats from outside-promises of ‘certain death’ for the IRGC or Basij if they do not lay down arms-are unlikely to switch many loyalties overnight. The state’s language of sacrifice and martyrdom runs deep in Shia tradition. After the reported killing of the Supreme Leader, state television announced days of mourning and crowds gathered with candles and phone lights. Even allowing for fear, that points to a civilian core that remains loyal.

Could an internal, pro‑Western coup short‑circuit the conflict? It is not impossible, but on day three most analysts judge it far less likely than a hard‑line hunkering down: more missiles launched under pressure, more risk‑taking, and a conviction in Tehran that it can absorb pain longer than its enemies. As usual, most of that pain lands on ordinary Iranians, who have the least say over events.

Air power alone rarely topples well‑armed regimes. In 2003, the US and UK removed Saddam Hussein with a ground invasion. In 2011, Nato and Gulf states enabled Libyan rebels from the air but it was fighters on the ground who ended Gaddafi’s rule. Bombing can erode capacity; it cannot, by itself, build a stable political order to follow.

So what are the plausible endgames? One is regime survival after severe damage, followed by long years of covert conflict around the region. Another is a negotiated pause that freezes lines but leaves grievances alive. A faster collapse could bring celebrations-and then the hard work of preventing fragmentation, reprisals and militia rule. Wars end; what comes next is usually the test that matters most for civilians.

Scale is the warning label. Iran is almost three times the size of Iraq and home to more than 90 million people from multiple ethnic groups. If institutions buckle, the confusion and bloodshed that follow could rival the worst phases of Syria’s and Iraq’s civil wars. Recent history teaches a harsh lesson: bringing down a state is far easier than building a peaceful alternative.

We should also track the regional spillover. Iran has targeted Arab US partners and neighbours across the Gulf. Britain has now permitted American use of UK bases. And, if confirmed, the reported Kuwaiti downing of three US F‑15Es shows how miscalculation is built into high‑tempo air wars, even among allies. Each of these threads can pull the conflict wider without anyone quite intending it.

If you are following this for class, here’s how to read the next few days. Watch for signs of elite fragmentation in Tehran-unusual resignations, commanders contradicting each other, or units refusing orders. Note where Israeli and US strikes concentrate: missile production, naval assets, or the networks that arm proxy groups. And keep asking who is doing the verifying: officials, independent monitors, or partisan channels.

Practise source criticism as events unfold. When leaders describe sweeping goals, ask what counts as success and how it would be measured. When claims clash with published intelligence assessments, mark the difference in your notes. And remember that dramatic words-destiny, liberty, redemption-often give way to negotiated endings that feel unsatisfying yet real.

In the end, President Trump’s wager is clear: enough force, alongside Israeli action and a popular uprising, can reset the Middle East. Many Iranians would cheer the end of the Islamic Republic. But the odds of landing in a safer order through war alone are steep, and the human costs are already rising. Our job, as readers and learners, is to keep our heads clear while the news accelerates.
