Egypt Cannot Stay Out of Saudi Arabia’s War, Whatever Iran Warns

The request grew out of a refusal. When Crown Prince Mohammed bin Salman met Sisi in Cairo, he explained that he had pressed Washington with everything he had to join the war in Yemen, and that Donald Trump had set one condition: American help would come only if the Israeli army took part. That was a demand for an Israeli military role, not intelligence sharing, and the crown prince turned it down. A military alliance is the hardest bond between two states, and fighting beside Israel would have been normalisation in all but name. He chose the longer and harder road, and came to Egypt. That is to his credit. Silent Dossier set out the background in how Riyadh chose Cairo over Israel.

Silent Dossier understands that the Saudi shopping list that followed is longer than previously known. Riyadh has asked Egypt for its Russian-made S-300 air-defence systems; RIM-7M surface-to-air missiles; the Egyptian-made Hares-1 and Hares-2 counter-drone systems; S-23 artillery; Rafale fighters; the Skyguard-Amoun air-defence system; and Egypt’s Patriot batteries.

Some of that list is less useful than it looks. Egypt operates the older Patriot PAC-2, while Saudi Arabia, which runs one of the largest Patriot forces in the world after the United States, already fields the PAC-3. The kingdom’s problem is not the number of batteries. It is the stock of interceptors it can fire, night after night, at Houthi missiles and drones. Whatever Egypt sends, it is preparing a transfer to Saudi Arabia on a scale it has not attempted in decades.

Egypt’s support comes with a condition. Silent Dossier understands that Sisi told the crown prince the war must stay in Yemen. The Iranian front must remain closed, even if fighting between the United States and Iran resumes, and Saudi Arabia must not join it. Saudi jets would not need to fly over Iran for that to happen. Opening Saudi airspace to American bombers would be enough to make the kingdom a party to that war.

Sisi has said the same in public, within the limits of public speech. Days before the parliamentary vote he said that “the Egyptian military effort is intended to defend the Kingdom’s territory and does not include an attack on Yemen,” adding: “We are speaking only about defence.”

The reason is arithmetic. An Iran war on top of the Yemen war would force Egypt to move far more equipment, at far greater cost, into a fight with a state rather than a militia. Every time Cairo merely debates the decision, the Egyptian pound feels it. A second front would multiply that pressure.

Yes, and Cairo should say so plainly to its own public. If Egypt commits ground forces to Saudi Arabia, it must expect Iran to treat it as a party. This time Tehran has made clear it could go further than missiles, with ground moves into neighbouring states such as Bahrain, Kuwait and Iraq.

Egypt’s likely assignments are two fronts. The first is the Yemeni border: if the Houthis, the Iran-backed movement that has held Yemen’s capital, Sanaa, since 2014, push into Saudi territory, Riyadh will ask Cairo for ground troops, and Egypt will send them. The second is Iraq, where Egypt would send air defences rather than soldiers. The Iran-aligned Shia militias in Iraq have done Saudi Arabia more damage than anyone else, striking the East-West pipeline more than once with drones that reach deep into the kingdom. Placing Egyptian forces on that front means putting fuel next to the fire between Cairo and Tehran.

Could the Houthis hit Egyptian infrastructure? They could. Could Iran target Egypt? It could. Iran has missiles with the range to reach Britain; it certainly has missiles that reach Egypt.

The danger is not only in Tehran and Sanaa. Egyptian television has started answering Houthi and Iranian threats in kind, with commentators on the evening news telling the Houthis not to test Egypt’s patience and promising a decisive response. That tone can drag a country into a stage of war it never chose. The Houthis are a terrorist militia; Egypt’s role is defensive, and its public voice should stay disciplined.

On 30 October the Saudi-led coalition said it destroyed a drone over the Mecca region. No sane person believes Saudi Arabia would fire drones at its own holy cities. The Houthis aim at Mecca and Medina to frighten pilgrims away and strike at the kingdom’s standing.

Egypt could have sat on the banks of the Suez Canal and counted money. Canal revenue is up 47 percent in the latest figures; in August alone the Suez Canal Authority reported $567.1 million, 56.7 percent more than a year earlier. Part of the reason is the Houthis themselves: by closing the Bab al-Mandeb strait to Saudi shipping, they pushed Saudi cargoes north through the canal, which has become the main route for the kingdom’s ships.

But a country that counts its earnings and tells itself the Gulf is none of its business has no guarantee the Houthis will not come for it next. Egypt has three more reasons to act.

About 1.5 million Egyptians live and work in Saudi Arabia. If Cairo washes its hands of the kingdom, many of them will eventually come home, into an economy that cannot absorb them.

Saudi investment in Egypt is real money with a real expectation behind it. It reflects brotherhood and friendship, and also a calculation that on the day Riyadh needs Cairo, Cairo will be there.

The most important reason is Israel. If Egypt steps back, Israel steps in. For nine months Egypt kept out of the Gulf war. Then the crown prince arrived and explained that Trump wanted Israeli forces fighting alongside the Saudis. Had Cairo said no, Israel would have taken Egypt’s place, its influence in the region would have grown at Egypt’s expense, and Egypt would have emerged far weaker. That is Egypt’s red line. Until the last moment Cairo will try to avoid this war and come out ahead on every count, but it will pay an economic price either way.

Egypt is moving military units to Saudi Arabia, but without public announcements. The reasons are visible. The pound falls every time the decision is merely discussed, so a public deployment would cost more. Egypt’s role is defensive, and Cairo does not want to provoke parties it hopes never to fight.

Egypt’s naval exercise with Türkiye (Turkey) matters here. It puts Egyptian and Turkish warships off the coast of Yemen, which is a message in its own right.

Ground troops are where Egypt draws the line for now. It will support Saudi Arabia with everything short of ground combat: air defences, fighters, naval forces. A formal Saudi request for ground forces would come only if the Houthis cross into Saudi territory, and if it comes, the cost to Egypt’s economy and currency will rise again.

On 28 October, Ethiopia’s prime minister, Abiy Ahmed, announced that his country had taken delivery of 12 Russian Su-35 fighters, a year ahead of schedule, and that four S-400 air-defence batteries would follow. The announcement came while Sisi was in Moscow for the Russia-Africa summit. Silent Dossier covered the Su-35 delivery separately.

The Su-35 is an air-superiority fighter built for combat against other aircraft, not for bombing ground targets. Ethiopia is fighting an internal war, and neither the Su-35 nor the S-400 helps with that. They are useful for protecting the Grand Ethiopian Renaissance Dam (GERD) on the Blue Nile, or for threatening Eritrea. Russia is also training Ethiopia’s navy, although Ethiopia has no coastline, and has promised it warships if it ever reaches the sea.

Behind the warm welcome in Moscow, Vladimir Putin is not playing straight with Egypt. The deal also drains Ethiopia’s economy. The longer Egypt waits on the dam, the greater the damage, and the more others use the dam as Egypt’s weak point. Even Donald Trump has said he cannot understand why the Egyptians stay quiet. Egypt cannot stay silent about the dam much longer.

Egypt and Iran have not had full diplomatic relations since 1980. Revolutionary Iran broke ties after Egypt made peace with Israel and gave refuge to the deposed Shah, who is buried in Cairo. Since then the two countries have kept only interest sections in each other’s capitals.

The last two years brought a thaw. Iran’s president, Masoud Pezeshkian, attended the D-8 summit in Cairo in December 2024, the first visit by an Iranian president in more than a decade. In September 2025 Egypt hosted the agreement between Iran and the International Atomic Energy Agency on resuming inspections, signed by Araghchi in Cairo with Egypt’s foreign minister, Badr Abdelatty, beside him.

The Houthi war on Saudi Arabia has tested that thaw. On 13 October Abdelatty called Araghchi and demanded an immediate halt to the attacks on the kingdom, and Egypt has since said it will give Saudi Arabia whatever support it asks for. Iran wants Egypt as a channel and a neutral party. Egypt wants calm with Iran, but not at the price of Saudi Arabia’s security. When those two aims collide, Cairo has already chosen.

Diplomacy is moving at the same time as the armies. On Trump’s instruction, Vice President JD Vance sent a letter to Mohsen Rezaei, a former commander of Iran’s Revolutionary Guard and now secretary of the country’s Supreme National Security Council. Washington appears to have concluded that the decision does not rest with the foreign minister, Abbas Araghchi, or the speaker of parliament, Mohammad Bagher Ghalibaf, but with the Revolutionary Guard. A hard-line deal needs a hard-liner’s signature. Tehran has not accepted the approach, and Silent Dossier has examined what the letter means before the US midterms.

Qatar is working the other channel, with Trump’s knowledge. Its negotiators found enough in talks with an Iranian delegation that, when the Iranians said they would return home and reply later, the Qataris refused to wait and flew to Tehran with them on 30 October. Pakistan says there are signs of progress.

That would be welcome. But Trump has vowed to strike Iran after the 3 November midterm elections. A war fought again with the same bombs, the same aircraft and the same plan will achieve nothing in the end. American strikes have wiped bases off the map, but Iran has absorbed them and is gaining ground diplomatically. On 26 October, in talks between Iran and the partners in the Mecca Joint Defence Agreement, Saudi Arabia’s defence minister, Prince Khalid bin Salman, Türkiye’s intelligence chief, Ibrahim Kalin, and Pakistan’s army chief, Field Marshal Asim Munir, sat down in Tehran. Before the war that scene was unthinkable. In this war Trump has hurt himself more than anyone.

If the war returns, Iran will not take its revenge on the United States, whose firepower it cannot match. It will take it on the Gulf. Trump promises a short operation of a few days, but the Gulf, with its economic visions, its megaprojects and its trading economies, cannot absorb what Iran is willing to absorb.
