Yemen: Drones Become a Double-Edged Sword, Raising Risks of a New War

Recent developments in Yemen have revealed a notable new trend: the Houthi group, which has long held an almost unchallenged advantage in drone warfare, is now beginning to face drone attacks from its adversaries on multiple fronts.

This does not mean the balance of power has shifted, nor that the Houthis have lost their edge in missiles and drones. But the increasing use of this type of warfare by forces loyal to the internationally recognized government could change the nature of the confrontation, especially if scattered operations are transformed into a more organized and sustainable capability.

For years, the Houthis have used drones as one of the most critical tools of their asymmetric warfare. They could track their opponents, strike staging areas, command centers, and facilities far behind the frontlines, while government forces were mostly on the defensive and tasked with interception. Today, that equation is no longer so simple.

In recent days, government-aligned forces have announced drone strikes on Houthi positions in Marib, al-Jawf, Taiz, Hajjah, al-Dhalea, and other frontlines, releasing videos of some of these operations.

It is still too early to speak of a balance in drone power. The Houthis have years of experience and a more advanced missile and drone infrastructure. However, the government does not necessarily need to achieve full parity to make a difference on the battlefield. If Houthi staging areas, vehicles, artillery, reinforcements, and command centers become vulnerable to attack, the group will be forced to change its deployment, movement, and supply tactics. In war, forcing an enemy to change its behavior is already a military achievement.

It would be a mistake to claim the Houthis have switched to a purely defensive posture. They are still conducting large-scale offensive operations: they are attacking Marib and Hadramout, repeatedly targeting al-Makha (Mocha), escalating against Saudi Arabia, and resuming activity in the Red Sea and Bab al-Mandeb. But there is a difference between a group in strategic defense and one beginning to act on some fronts as if it must prepare for the possibility of being attacked.

The geography of recent attacks matters more than their sheer number. Marib, Taiz, al-Makha, and the western coast are not random frontlines; they represent key gateways for any potential ground war.

Marib is the eastern gateway and one of the government's most critical military and political centers. Taiz is a central and coastal crossroads, where activating frontlines can tie down large forces. Al-Makha and the western coast carry different significance: to the south lies Bab al-Mandeb, to the north a road stretching to Hodeidah. Repeated attacks on al-Makha with missiles and drones may be a test of a front that could become highly important if ground operations begin along the coast.

Considering what is happening in Marib, Taiz, al-Makha, al-Dhalea, al-Jawf, Saada, and Hodeidah together, it is hard to view each front as an isolated incident. This does not mean a decision for a ground war has been made, but it does suggest the parties are beginning to act as though this possibility must be taken seriously. The most critical indicator in the coming period will not be the number of missiles or drones, but the movement of forces, reserves, and ammunition. When that movement starts concentrating on a specific axis, we will move from 'testing' frontlines to 'preparing' them.

In this context, recent statements by Presidential Leadership Council Chairman Rashad al-Alimi must be read correctly. Al-Alimi called on the Houthis to lay down arms and engage in political life, but also stated that no Houthi action would go without a comprehensive response or deterrence. He outlined the strategic objective of restoring state institutions, emphasizing sustainable peace based on the state's monopoly on weapons and sovereignty.

If these statements are not backed by action, they may be dismissed as political rhetoric. But what gives weight to al-Alimi's latest message is what is happening on the ground: government drones have been publicly used in confrontations, artillery is active on multiple fronts, military readiness has increased, and the government is speaking more clearly about deterrence. The real test for the government is whether these moves become a sustainable operational doctrine, whereby every Houthi attack incurs a direct cost, or whether the old pattern persists—government forces absorbing blows and responding only in a limited manner.

All this unfolds against a wider regional backdrop. The chaos in the Strait of Hormuz and the U.S.-Israeli war against Iran are raising the strategic value of the Red Sea. The less secure Hormuz becomes, the more important Saudi Arabia's western energy and trade routes turn. Bab al-Mandeb's value automatically rises as a card in Houthi hands. The geographic equation is complex: Iran can pressure Hormuz, the Houthis can threaten Bab al-Mandeb, and Saudi Arabia sits strategically between the two corridors.

In response, Riyadh is working on agreements to protect the Red Sea, while Yemeni government forces are showing more active operations on the ground. This could lead to a different formula than the previous war: Yemeni forces take on the bulk of ground confrontation, while Saudi Arabia and its partners provide support, deterrence, and protection of maritime routes.

The danger is that all parties are moving closer to the brink of war: the Houthis are testing how much pressure they can exert on Saudi Arabia, the Yemeni government, and international shipping; government forces are testing new tools and their ability to regain the initiative; Saudi Arabia is trying to build a new deterrence capability; and the U.S.-Iran confrontation continues in the background. This widens the margin for strategic miscalculations that could lead to an open war.
