IRAN WAR: Iran’s Regional Network Reshapes the Middle East

When people talk about  the Iran war, we tend to focus on Iran itself: the nuclear program, the Hormuz Strait struggles, how any American strikes there was. However, the war is now slowly expanding to other places, and the most important consequences of the war are happening also somewhere else. 

Across Lebanon, Yemen and Iraq, armed groups connected to Iran are fighting, reorganizing and adapting to a rapidly changing Middle East. These fronts are not simply side battles. They are part of a wider contest over who will shape the region after the current war ends.

In this week’s blog post, let’s look at Iran’s network across the region and ask whether it can survive the war with America.

IN LEBANON, HEZBOLLAH’S PROBLEM IS NO LONGER SIMPLY ISRAEL

For a long time, Hezbollah has been an important part of Iran’s regional strategy. Its political and military influence in Lebanon gave Tehran a powerful partner right on Israel’s northern border. Over the years, Hezbollah built a large arsenal of rockets and missiles, an extensive network of tunnels and a lot of battlefield experience.

But that balance has changed.

The fighting in southern Lebanon now comes down to two main questions. One is Israel’s security. The other is whether the Lebanese state can regain control over weapons in the country. Israel wants Hezbollah pushed away from the border and ultimately disarmed. Lebanon’s government has also called for the state to have full control over weapons, while demanding that Israel withdraw from Lebanese territory. Hezbollah, however, has refused to give up the military capabilities that have been at the centre of its power for decades.

This creates a difficult situation. If Hezbollah disarms while Israeli forces remain in southern Lebanon, it risks giving up much of its leverage without getting an Israeli withdrawal in return. If it refuses to disarm, Israel has made clear that it is prepared to continue its military pressure.

Iran is also deeply involved. Reports indicate that Iran’s Revolutionary Guard has been helping rebuild and finance Hezbollah’s military capabilities. Hezbollah remains one of Tehran’s most important regional partners and continues to depend heavily on Iranian support.

THE GEOGRAPHY OF THE HOUTHIS MATTERS IN YEMEN

If Hezbollah represents Iran’s traditional model, a powerful armed group positioned close to Israel, the Houthis offer Tehran something different. They offer geography.

The Houthis have made major gains along Yemen’s Red Sea coast, including the port of Mocha and the strategic Perim Island at the entrance to the Bab el Mandeb Strait. This puts them in a position to threaten one of the world’s most important maritime routes.

And that is what makes Yemen so important.

After years of relative calm, fighting in Yemen has intensified again. Houthi forces have advanced against government aligned forces, while Saudi Arabia has responded with airstrikes. The fighting has also caused a new wave of displacement.

The consequences go far beyond Yemen. Bab el Mandeb connects the Red Sea with the Gulf of Aden and is part of the main shipping route between Asia and Europe through the Suez Canal. If shipping through the area becomes too dangerous, companies may have to take longer routes around Africa. That means higher fuel, insurance and transportation costs.

For Iran, this creates another source of strategic pressure. Tehran does not need to control the shipping route itself. Having an aligned armed group positioned near the Bab el Mandeb gives Iran another way to threaten an important route for global trade and energy.

That makes Yemen more than another battlefield. With the Houthis expanding their presence around the Bab el Mandeb, the country has become an increasingly important part of the wider regional conflict.

IRAQ, THE BRIDGE BETWEEN IRAN’S ALLIES

Iraq is a less visible front, but it could become one of the most important. The country is home to powerful Iran aligned armed groups, many of which operate within the Popular Mobilization Forces, Iraq’s state security structure.

For years, these groups have given Tehran influence in Iraq without requiring Iran to deploy its own conventional forces. But their role is becoming more significant as the wider regional conflict expands.

There is now evidence of growing coordination between Iraqi armed groups and the Houthis. Iraqi groups have been linked to attacks on US and Saudi targets, while recent reporting points to coordination between Iraqi militias and the Houthis. This suggests that Iran’s regional partners are increasingly capable of operating across different fronts.

That does not mean these groups operate as a single organization. They have their own leadership, interests and local agendas. But they share close ties with Tehran and, in some cases, cooperate on weapons, intelligence and military operations.

For Iraq, this creates a difficult position. Baghdad is trying to maintain its relationship with Iran while also building closer economic and security ties with the United States and the Gulf states. At the same time, the Iraqi government is facing pressure to bring Iran aligned armed groups more firmly under state control.

The danger for Iraq is that its territory could increasingly become part of a wider regional conflict. If Iraqi armed groups continue launching attacks against targets outside the country, Baghdad could face retaliation and become more deeply involved in a war it is trying to avoid.

THE OLD “AXIS OF RESISTANCE” IS CHANGING

For years, Iran’s regional strategy was often described as an “Axis of Resistance.” The idea was relatively simple. Tehran supported governments and armed groups across the Middle East that could put pressure on Israel and the United States without Iran having to fight every battle itself. 

But the map has changed!

Hezbollah has been significantly weakened, Iran lost its most important position in Syria after the fall of Bashar al Assad, and the land route that once connected Iran through Iraq and Syria to Lebanon is no longer as secure as it was.

That does not necessarily mean Iran’s regional network is disappearing. It may be adapting.

Iraq and Yemen have become increasingly important. Iraqi armed groups give Tehran influence around the Gulf, while the Houthis give Iran an aligned force positioned near the Red Sea and the Bab el Mandeb. Recent fighting has shown that these groups can put pressure on different parts of the region at the same time.

The network is therefore becoming more spread out. The groups are not controlled from a single command centre, and they have their own interests and political calculations. But their connections to Tehran give Iran several different ways to project influence across the region.

THE DANGER OF A MULTI FRONT WAR

This is where the situation becomes more complicated.

The longer the conflict continues, the greater the chance that events on one front affect another. Fighting in Lebanon could lead to a response from Iran. Attacks by Iraqi armed groups could bring U.S. or Israeli retaliation. The Houthis could increase attacks on Saudi Arabia or threaten shipping in the Red Sea.

We are already seeing some of these fronts interact. Recent fighting in Iraq has involved Iran aligned militias, while the Houthis have expanded their presence along Yemen’s Red Sea coast and attacked Saudi targets.

That creates a dangerous cycle. An attack on one front can trigger a response somewhere else, which can then produce another round of escalation.

Iran does not need to control every group directly for this to matter. Hezbollah, the Houthis and Iraqi armed groups all have their own interests and operate with different degrees of independence. But their shared relationship with Tehran means that pressure on one part of the network can have consequences elsewhere.

That is what makes a wider regional war so difficult to contain.

The Middle East is no longer facing a single conflict with a few disconnected fronts. The conflicts are increasingly overlapping, with Lebanon, Iraq, Iran and Yemen all connected to the wider confrontation.

And that makes the next stage of the war much harder to predict.

CONCLUSION 

The Iran war will be judged by more than what happens inside Iran. What happens in Lebanon, Iraq and Yemen could be just as important in determining whether Tehran’s regional network is weakened, transformed or rebuilt.

The war may eventually end, but the conflict could continue in a different form. If Iran manages to preserve influence through its regional partners, the Middle East may be entering a new phase — one where the battlefield is no longer centered on Iran, but spread across the region.
