  • Senior security officials assess that the Houthis in Yemen are likely to expand the conflict. They may target maritime traffic in the Red Sea and try to disrupt navigation through the Bab al-Mandeb Strait in support of Iran.
  • Iran appears to be pursuing a “pincer strategy” focused on the Strait of Hormuz and Bab al-Mandeb to intensify economic pressure and halt the war.

The Houthis’ announcement that they are joining the war alongside Iran did not come as a surprise to Israel. According to a senior political source, the Israeli security establishment had long considered this scenario highly probable and had prepared accordingly.

This is not a limited tactical move, but rather a strategic step with broad implications. For nearly a month, Ansar Allah’s leadership maintained a cautious, almost hesitant stance, despite its supportive rhetoric toward the so-called “Axis of Resistance.”

However, once it became clear that the confrontation between Iran, Israel, and the United States was expanding into a wider regional conflict, the group recalibrated its risk assessment.

The first launch toward southern Israel caused no significant damage. Still, it marked the transition from rhetoric to action. This move completed the entry of all “Axis of Resistance” components into the conflict.

This development reinforces regional alignment around Iran while simultaneously raising the risk of broader escalation.

Senior security assessments suggest the Houthis’ primary objective is not necessarily Israel. Experience from recent years shows that their most effective tool is disrupting navigation in the Red Sea and the Bab al-Mandeb Strait.

This waterway is a critical artery for the global economy, particularly for oil shipments and goods bound for Europe. Any disruption, even a partial one, immediately translates into rising energy prices and instability in global supply chains.

With the Strait of Hormuz already under pressure, Bab al-Mandeb’s involvement compounds global risks.

The Houthis exert indirect economic pressure instead of direct confrontation, leveraging their advantage.

It is difficult to separate the Houthis’ actions in Yemen from Iran’s broader strategic framework. Iran has long signaled it can expand conflict across multiple arenas without direct engagement in each one.

Within this context, the Houthis function as a proxy force, though not one entirely devoid of independent decision-making.

Iran’s simultaneous pressure at Hormuz and Bab al-Mandeb aims to amplify the global economic crisis and end the war.

At the same time, the Houthis’ decision to join the conflict at this stage also stems from their own internal calculations.

Ansar Allah’s leadership likely judged that restraint could hurt their standing in the Axis of Resistance. Joining the conflict lets them reassert their regional role, not just as a local Yemeni force.

Despite their disruptive potential, it is important to recognize the limits of Houthi military capabilities. They do not exercise full control over the Bab al-Mandeb Strait and lack the advanced naval assets required to completely shut down maritime routes.

Security officials say full control is not needed for impact. A few targeted attacks or a sustained threat may be enough to reroute vessels, raise costs, and inject market uncertainty.

In other words, the gap between military capability and economic impact works in the Houthis’ favor.

The Houthis’ entry into the conflict is therefore not merely an addition of military support for Iran, but a qualitative shift in the nature of the confrontation.

It opens a primarily maritime front and heightens the risk of escalation from the Persian Gulf to the Red Sea.

At the same time, this presents the international community with a dilemma. They must safeguard freedom of navigation without getting drawn into direct military involvement in Yemen.

A lack of international consensus may encourage further escalation. This can create a vacuum where actors pursue their own interests.

Conclusion

The Houthis’ entry into the war, while not decisive in itself, carries a significant cumulative impact. Key takeaway: their involvement strengthens Iran’s multi-front pressure strategy by exploiting vulnerabilities in the global economy, demonstrating how third-party actions can magnify the global effects of regional conflicts.

In summary, while the Houthis’ entry does not alone determine the conflict’s outcome, their involvement adds a new layer of complexity and risk. This move amplifies Iran’s pressure tactics and further destabilizes the region, making it crucial for the international community to address the dual challenges of maritime security and regional escalation in this evolving situation.
