As Yemen passes 15 years of devastating conflict, the country faces renewed risk of escalation amid the widening regional confrontation involving Iran, Israel and the United States. After weeks of speculation over whether Yemen's Houthis would remain on the sidelines, the movement launched ballistic missile attacks toward Israel on March 28. While the limited nature of the assault suggests an attempt to signal alignment with Iran's regional posture without triggering full-scale retaliation, the question now is whether Houthi thinking remains limited to this signaling or reflects the beginning of a sustained escalation, once again making Yemen an active front in the Middle East's expanding conflict.
The depth of the relationship between Iran and the Houthis is central to this question, constituting one of the most contested debates surrounding the group. For some analysts, the movement operates as a crucial component of Tehran's regional network of allied militias. "The Houthis always try to present themselves as independent decision-makers," said veteran Yemeni journalist Anwar al-Ansi in an interview with Democracy in Exile. "But we know there has been a very close ideological and military relationship with Iran for nearly three decades."
According to al-Ansi, the group's military capabilities — from ballistic missiles to drones and naval mines — were developed largely through training and assistance from Iran's Revolutionary Guards (IRGC) and Lebanon's Hezbollah. "Without Iranian weapons, the Houthis would not be what they are today," he said.
Numerous reports highlight how Iranian military support to the Houthis has grown over the course of the war in Yemen. The United Nations Panel of Experts on Yemen found in 2018 that Iran "failed to take the necessary measures to prevent the direct or indirect supply, sale or transfer" of various ballistic missiles that the Houthis have used to perpetrate unlawful attacks. As a result, Iran agreed to significantly reduce its support for the Houthis in the March 2023 China-brokered deal re-establishing diplomatic relations between Saudi Arabia and Iran.
Other experts describe the relationship in broader strategic terms. Nadwa al-Dawsari, a veteran Yemeni researcher, argued in an interview that the movement functions within a transnational project tied to Tehran's regional ambitions. "The Houthis are a transnational group," she said, explaining that "Yemen, for them, is a base where they organize, regroup and launch cross-border operations." In her view, the IRGC maintains significant influence over the group.
Yet not all analysts see the Houthis as mere proxies. Speaking in an interview for Democracy in Exile, historian and instructor at Harvard University, Asher Orkaby, notes that Yemeni political movements — particularly the Houthis — have historically shifted alliances based on power calculations rather than ideological loyalty. "The Houthis have continuously backed the winning party," he said. "What they understand is power — military power and financial power."
In "Beyond the Arab Cold War: The International History of the Yemen Civil War, 1962-68," Orkaby documents how Zaydi royalist forces drawn from the same northern highland communities and religious tradition that later gave rise to the Houthi Movement relied on shifting external support for survival. Backed primarily by Saudi Arabia and, at times, covertly by Israel, these actors navigated alliances pragmatically rather than ideologically. Most notable is the group's brief tactical alliance with the former Yemeni president, Ali Abdullah Saleh, despite having fought multiple rounds against him in the Saada Wars that precluded Yemen's civil conflict.
That alliance was derived purely out of self-interest. The Houthis needed access to state military networks and resources in their effort to conquer the state. Once they secured this objective, they turned on Saleh — killing him in 2017.
Orkaby argues that the Houthis similarly rushed to support Gaza because the group understood they would gain more than lose, winning the hearts and minds of people at home and abroad. That pragmatism may explain their delayed decision to join Iran's confrontation with Israel and the United States, even as other Iranian partners across the region have been weakened or sidelined.
For Orkaby, the Houthis may have been calculating the broader geopolitical balance. With several Iranian allies diminished in recent years, the group may hesitate to tie its fate too closely to Tehran. "They understand that Iran is a sinking ship," he explained.
Early Houthi restraint appeared to be driven by a combination of Iranian strategy and the group's domestic calculations. Al-Dawsari believes Tehran initially preferred to keep the group out of the war unless absolutely necessary. "Iran has lost most of its proxies, and now the Houthis represent the proxy with the most potential to support Iran's regime," she said. Preserving the Houthis was intended as a strategic priority. "The Houthis will likely intervene more fully only in the event of an existential threat to Iran's regime," she argued before the group launched strikes at Israel.
Al-Ansi points to the risks the movement could now face upon entering the conflict, especially if they do so more aggressively. In this regard, intelligence services in Washington and Tel Aviv have spent years gathering detailed information about Houthi military infrastructure. "If the Houthis begin aggressively attacking Israel or U.S. targets again, the response will be much stronger than before," he warned. One example of the devastating consequences of Israeli retaliation against the Houthis is the killing of most of the Houthi group's cabinet members in an August 2025 attack on Sana'a.
The group also faces domestic constraints. Despite controlling the capital and much of the north, the Houthis remain under economic pressure and international isolation. "Their situation is extremely difficult," al-Ansi said. "They are under sanctions, isolated internationally and face hostility even within areas they control." Last year, the United States re-designated the Houthis as a Foreign Terrorist Organization and a Specially Designated Global Terrorist, deepening economic pressure, albeit likely marginally compared to sweeping aid cuts to Yemen around the same time.
If conflict between Iran and its adversaries escalates, Yemen could quickly become a key theater, with renewed attacks on Red Sea and Bab al-Mandeb shipping — disruptions that would again amplify global economic pressure, as in 2024–25.
In an interview for Democracy in Exile, Yemeni academic and political analyst Abdulwahab Al-Awaj said that energy infrastructure in Gulf states could also become targets for the group. "The Houthis could attack fuel infrastructure in Saudi Arabia," he said. Al-Awaj added that such operations would likely begin from areas like Hodeidah and Ibb, where the Houthis have increasingly mobilized their forces, if Iran gave the green light.
For Yemen itself, the regional crisis could prolong the stalemate that has defined the war since a fragile truce emerged in 2022. Still, peace negotiations remain distant. Al-Dawsari argued that the Houthis have historically engaged in diplomacy to primarily buy time rather than to reach a genuine settlement: "They have never engaged in good faith in the peace process."
Meanwhile, the anti-Houthi camp has begun reorganizing after years of internal divisions. According to Al-Awaj, Saudi Arabia is working to unify Yemeni forces and assume greater control over key fronts following the United Arab Emirates' reduced role in the conflict. However, any decisive shift on the battlefield may depend on events far beyond Yemen's borders. As al-Ansi explained, the country now finds itself suspended between war and peace, waiting for the regional picture to clear.
The Houthis seem to be demonstrating a calibrated entry rather than a full escalation. What happens next will depend not only on those calculations, but on how forcefully regional actors respond. One fact is clear, however: Another critical front may be opening in this worsening regional war.
