The Middle East is now waging war on an eye-for-an-eye, tooth-for-a-tooth basis

The brief

“An eye for an eye” describes retaliation: one side answers an attack with a similar attack. In this conflict, the phrase explains how the Houthis justify hitting Saudi Arabia after Saudi forces bombed Sana’a. It also shows how each side’s military actions deepen the other side’s willingness to continue fighting. The article says the Houthis have fired ballistic missiles, cruise missiles, and drones at Riyadh’s airport. They have done so daily since Saudi Arabia joined the civil war in October. Mäkelä says the Houthis are responding to Saudi bombing of Yemen’s capital. The Houthis also struck the Yemeni president’s palace, killing at least five people and injuring 16. This retaliation creates a cycle rather than a solution. Saudi attacks produce Houthi counterattacks, while Houthi strikes increase pressure on Saudi Arabia and its allies. The article warns that wider foreign involvement could expand the war and destabilize the Middle East further.

What does “an eye for an eye” mean in this conflict, and how are Houthi attacks presented as retaliation for Saudi bombing?

“An eye for an eye” describes retaliation: one side answers an attack with a similar attack. In this conflict, the phrase explains how the Houthis justify hitting Saudi Arabia after Saudi forces bombed Sana’a. It also shows how each side’s military actions deepen the other side’s willingness to continue fighting.

The article says the Houthis have fired ballistic missiles, cruise missiles, and drones at Riyadh’s airport. They have done so daily since Saudi Arabia joined the civil war in October. Mäkelä says the Houthis are responding to Saudi bombing of Yemen’s capital. The Houthis also struck the Yemeni president’s palace, killing at least five people and injuring 16.

This retaliation creates a cycle rather than a solution. Saudi attacks produce Houthi counterattacks, while Houthi strikes increase pressure on Saudi Arabia and its allies. The article warns that wider foreign involvement could expand the war and destabilize the Middle East further.

02

Who are the Houthis, and which parts of Yemen do they control?

The Houthis are a Yemeni armed movement that has become a major military force. The article describes them as the dominant military power in Yemen. Their rise matters because they control the capital and a large population, making them difficult for the internationally recognized government and its foreign supporters to defeat.

The Houthis control Sana’a, Yemen’s capital, and much of the country’s north. Their territory is estimated to contain 60–65 percent of Yemen’s population. They are also fighting hard to capture Taiz, Yemen’s third-largest city. Their forces have developed from small armed groups into an organized and well-equipped army.

The article estimates that the Houthis have 250,000–350,000 fighters. Iran and Lebanon’s Hezbollah are said to have armed and trained them. The Houthis have also carried out increasingly accurate attacks, possibly helped by Iranian intelligence about targets. Their control and military strength make a quick military victory unlikely.

03

Why did Saudi Arabia enter Yemen’s civil war, and what role is the internationally recognized Yemeni government playing?

Saudi Arabia joined Yemen’s civil war in October, and the article presents this involvement as connected to defending Saudi territory from Houthi attacks. Saudi Arabia has since faced missile and drone strikes, including attacks on Riyadh’s airport. Its intervention matters because it transformed Yemen’s internal conflict into a regional confrontation involving several outside powers.

The internationally recognized Yemeni government is the main local force opposing the Houthis. It began an offensive campaign last week to retake areas under Houthi control. Government forces captured ground near Bab al-Mandab, an important sea passage. Fighting has intensified as the government tries to regain territory and the Houthis attempt to hold or expand their areas.

Saudi Arabia is supported by a multinational coalition. Britain and France have provided support, while Pakistan and Turkey signed a defense agreement with Saudi Arabia in August. Pakistan’s air force has fought the Houthis, and Pakistan has promised 40,000 soldiers. The government’s campaign therefore depends heavily on regional and international backing.

04

How large is the conflict, in terms of Houthi fighters, territory controlled, and people displaced from Taiz?

The conflict is large in both military and human terms. The Houthis are estimated to have 250,000–350,000 fighters. They control Sana’a and much of northern Yemen, including territory where 60–65 percent of Yemen’s population lives. This gives them a powerful base and makes the war more than a limited rebellion.

The fight for Taiz illustrates the scale of the battlefield. Taiz is Yemen’s third-largest city, and the Houthis are battling to capture it. A government source says 80,000 people have fled the city because of the fighting. The conflict therefore affects major urban areas as well as military positions near important routes.

The numbers also explain why outside intervention has not quickly ended the war. Saudi Arabia has the region’s largest and strongest army, but the Houthis remain a substantial, organized force. Their control of populated territory, foreign support, and ability to launch accurate attacks all point to a prolonged conflict.

05

What could happen to Yemen and the wider Middle East if Saudi Arabia, the United States, Iran, and more foreign forces become directly involved?

If Saudi Arabia, the United States, Iran, and additional foreign forces become directly involved, Yemen’s war could expand beyond its current battlefield. More countries would bring weapons, troops, air power, and competing strategic goals. That matters because every new participant could make compromise harder and increase the risk that attacks spread across borders.

The article gives several warning signs. Saudi Arabia wants American help, especially interceptor missiles, but also fears that joining the coalition would widen the war. Pakistan has already sent forces, Britain and France have provided support, and Turkey supplies defensive capabilities. Iran supports the Houthis through weapons, training, and possibly intelligence. These links connect Yemen’s fighting to wider rivalries.

The immediate consequences could include greater instability in the Middle East and more civilian deaths. Mäkelä says Iran might launch preemptive strikes against its enemies. He also expects developments before the United States midterm elections. The article does not predict one definite outcome, but it portrays escalation as a serious risk.

06

Why can a militarily stronger country such as Saudi Arabia still struggle to defeat a well-organized force fighting over difficult territory?

Military strength does not automatically produce victory. Saudi Arabia has the region’s largest and strongest army, but the article says it was organized mainly to protect the state from internal military coups. That structure may limit its effectiveness against a persistent force operating in Yemen’s difficult terrain and among populated areas.

The Houthis have adapted over time. They developed from small armed groups into an organized, well-equipped army with an estimated 250,000–350,000 fighters. They control Sana’a and much of northern Yemen, and they have made increasingly accurate missile and drone attacks. Their knowledge of local territory and ability to sustain resistance help offset Saudi Arabia’s conventional advantage.

Saudi Arabia already conducted broad bombing operations in 2015, but failed to defeat the Houthis. Mäkelä says the sides could continue a war of attrition indefinitely. He argues that the conflict cannot be solved militarily and needs an outside mediator, possibly China or Egypt.

07

What is a proxy war, and how can outside powers support local fighters without formally fighting one another directly?

A proxy war is a conflict where outside powers pursue their rivalry through local forces. They may provide weapons, training, intelligence, money, or military support without formally declaring war on one another. The local fighters do the main fighting, while foreign sponsors influence the conflict from behind the scenes. This explanation uses the established meaning of the term; the article describes the support relationships but does not use the phrase itself.

In Yemen, the article says Iran and Lebanon’s Hezbollah have armed and trained the Houthis. It also says Iran may provide intelligence about targets, helping the Houthis make more accurate attacks. On the other side, Saudi Arabia leads a multinational coalition supporting the internationally recognized Yemeni government. Britain, France, Pakistan, and Turkey are involved in different ways.

This arrangement lets foreign powers compete while limiting direct attacks between them. The United States and the Houthis had previously agreed not to attack each other, even as Washington considered supporting Saudi Arabia. Such indirect involvement can prolong the war and make a negotiated settlement more difficult.
