In June, U.S. President Donald Trump floated an extraordinary proposal to deal with Hezbollah: Syria should enter Lebanon and finish off the group. Few leaders had more reason to oblige than Syrian President Ahmed al-Sharaa. Hezbollah had spent years fighting alongside Bashar al-Assad’s forces. Even after Assad’s fall, the group continued to sow instability across Syria’s western border. Damascus had every reason to settle the score, and Sharaa still refused. He insisted that his government sought cooperation with Syria’s neighbor, not another war.
Four months later, Sharaa appears to be contemplating a foreign intervention, this time more than a thousand miles from home. Following Sharaa’s Oct. 6 meeting with Saudi Crown Prince Mohammed bin Salman in Riyadh, Axios and Reuters reported that the Saudis were seeking Syrian military assistance against the Houthis in Yemen, where Saudi-backed forces have been battling the group since early September. This reporting suggested that Sharaa, with U.S. approval, might be inclined to accept the Saudi request and deploy as many as 20,000 soldiers, including troops for offensive operations. Washington is said to have approved of the plan. Other sources have claimed that approximately 1,500 Syrian fighters have already arrived in Saudi Arabia and that Syrian drone operators are present in the southern coastal city of Aden.

Syria’s fractured and under-equipped military is unlikely to change the course of the war in Yemen. Still, its participation could have profound consequences at home: exposing Damascus to retaliation by Iran and its regional allies, undermining the government’s promise to keep Syria out of foreign conflicts, and threatening the country’s economic recovery. Rising energy prices are already fueling domestic protests, while the country remains desperate for foreign investment. The irony is that the countries investing in Syria may now be pushing it into a war that could jeopardize its stability.
Damascus is susceptible to this kind of pressure because its recovery from more than a decade of civil war depends on the goodwill of its partners. Saudi Arabia has emerged as one of Syria’s most important political and financial backers, pledging billions of dollars in investment. Riyadh’s partners in the Mecca Pact also provide the support Damascus desperately needs. Turkey is helping to rebuild the Syrian military, while Pakistan has reportedly become a supplier of weapons to replenish an arsenal devastated by Israeli strikes after Assad’s fall in December 2024. These partnerships have helped Sharaa rebuild Syria’s regional standing, but they have also left Damascus increasingly dependent on these countries.
Since taking power, Sharaa’s foreign policy has focused on balancing regional powers. Syria is drawing closer to Saudi Arabia but continues to maintain a strong relationship with the United Arab Emirates. Syria is deepening military cooperation with Turkey while signaling to Israel that it wants a comprehensive peace agreement. Damascus’s logic is to court competing powers without committing to one camp. At the same time, it seeks to benefit from these relationships without becoming entangled in their rivalries.
But that flexibility is becoming harder to sustain as the countries financing Syria’s recovery and rebuilding its military begin to expect something in return. For Riyadh, a Syrian deployment to Yemen could serve as a test of how far Sharaa is willing to go in supporting Saudi security interests. After investing considerable political and economic capital in Syria, Riyadh now expects Damascus to show it’s aligned with Saudi regional security interests and willing to repay the support it has received.
There is also a military calculation for Saudi Arabia in having Syria join the fight in Yemen. Despite their superior weapons, resources, and manpower of around 300,000 fighters, the Saudi-backed forces have struggled to dislodge the Houthis from their strongholds or achieve decisive territorial gains. Syrian fighters, particularly the battle-hardened formations that spearheaded the offensive against Assad, may offer what the Saudi-backed forces have lacked.
But winning a war in Syria does not mean knowing how to fight one in Yemen. The fighters who toppled Assad were operating on familiar terrain against a demoralized army. In Yemen, they would confront a Houthi movement that has spent years fighting on its own territory and has entrenched itself in mountainous strongholds. Syrian forces have no comparable experience in Yemen, lack much of the heavy equipment needed for a sustained campaign, and would face an enemy with a decisive terrain advantage.
The first casualty of a Syrian intervention could be the foreign-policy restraint that Sharaa has championed since Assad’s fall. After years of civil war, the leadership promised its people that it would “remain outside any conflict.”
Assad’s defeat dealt Iran one of its greatest strategic setbacks; after spending $50 billion supporting the regime, Tehran lost its strategic foothold in Syria, and its vital weapons corridor to Hezbollah was compromised. Sharaa has since sought to keep Syria out of a direct conflict with Iran and its proxies in order to avoid a confrontation that could give them pretext to destabilize his country. Joining the Saudi-led campaign against the Houthis would likely place Syria back in Iran’s crosshairs.
In March, the Iraqi Resistance Coordination Committee, an umbrella grouping of Iran-backed militias, warned Sharaa that Syrian involvement against Iran’s allies would amount to “a declaration of war against the entire Axis of Resistance.” The group threatened to turn Syria into an “open battlefield.” In July, a former Iranian official went further, threatening that intervention against Hezbollah in Lebanon would invite Iranian missile and drone attacks against Syria.
As reports of a possible Syrian deployment in Yemen began circulating, those warnings became more direct. Former Iraqi Interior Minister Baqir al-Zubaidi, a former member of the Iran-aligned Badr Organization, threatened that if Sharaa deployed troops, Syria could face “devastating Houthi strikes” and attacks “from other fronts.” The Houthis have already begun preparing the narrative for their confrontation with the Syrians. A Houthi-aligned Yemeni outlet portrayed the possible arrival of Syrian soldiers as a tool to transform the conflict into an “existential sectarian confrontation.”
Syrian government troops fighting the Houthis—who follow Zaydism, a branch of Shiite Islam—would offer the movement an opportunity to recast the conflict over territory as a sectarian struggle against foreign Sunni extremists. The arrival of Syrian fighters could become a powerful recruiting and mobilization tool. Pro-Iranian axis accounts have already depicted Syria’s military as a mercenary force available to whichever foreign government is willing to pay, a charge with implications for Syria’s reputation across the region.
Already, the prospect of sending troops to Yemen has unsettled Syrians themselves. Some have undeniably welcomed the prospect of intervention, arguing that Syrians and Yemenis were fighting the same Iranian-backed forces that had devastated their countries. But many others, including those who have little sympathy for Iran or the Houthis, are concerned. “Syrian blood is … not for sale,” one Syrian commentator declared, calling the proposed deployment “unacceptable.” Another raised the specter of Iranian retaliation: “If we fight the Houthis and Iran responds by bombing us, who will stop it?” Or as yet another declared on X: “This is sheer stupidity to enter a war that is none of our concern.”
There is no available polling that directly captures Syrian attitudes toward a military intervention in Yemen. But existing surveys show that reluctance to fight another war extends beyond online spaces. An April poll found that 63 percent of respondents opposed Syrian military intervention in Lebanon. A February survey revealed that only 5 percent of Syrians favored a military response against Israeli incursions in southern Syria.
Trump has repeatedly pledged to give Syria a “chance at greatness,” remove all barriers to rebuilding Syria, lift all sanctions, and let foreign investment pour into the country, betting that economic recovery will create the stability needed to transform Syria into a dependable partner. Yet Washington is now appearing to jeopardize that progress for the prospect of a few thousand soldiers fighting the Houthis. U.S. officials may see the Syrian deployment as a chance to strengthen the Saudi-led campaign without committing U.S. forces. But the military benefits of Syrian participation are uncertain, and the costs of a regional confrontation and instability could undo one of Washington’s most significant achievements in Syria.
The same applies to Saudi Arabia. Riyadh has pledged billions of dollars toward Syria’s reconstruction, betting that the country’s recovery will create new economic opportunities. Yet these investments will only return if stability holds.
This is a true foreign-policy test for Sharaa; his decision will ultimately define what kind of regional partner he wants Syria to become. He has worked to convince foreign governments that Syria is a country worth investing in, but that will be harder if he begins sending troops into wars far beyond its borders.
