Meetings between Syrian President Ahmed al-Sharaa and U.S. President Donald Trump on the sidelines of the NATO summit in Ankara marked a significant shift in relations between Washington and Damascus, signaling that the U.S. opening toward Syria extends beyond lifting sanctions and into a broader regional security framework centered on Iran, Hezbollah and Israel's security.

While Trump's announcement that the United States would remove Syria from its list of state sponsors of terrorism dominated headlines, the discussions also highlighted the conditions Washington is expected to place on Damascus as Congress reviews the decision.

The decision to hold the meetings in Ankara carried broader geopolitical significance than simple diplomatic protocol.

The Turkish capital underscored Ankara's position as the foreign power with the greatest influence over Syria's new leadership and as Washington's preferred partner for gradually integrating Damascus into a wider Western-backed security and political architecture while maintaining clear U.S. and Israeli safeguards.

Although al-Sharaa did not participate in NATO's proceedings and Syria is not a member or partner of the alliance, his presence in Ankara effectively brought Damascus closer to the Western security environment through Turkey.

Ankara is seeking to leverage its influence within NATO and across the Middle East, while Washington increasingly views Syria as part of a broader regional strategy that extends beyond sanctions relief to include Iran, Hezbollah, border security and Israel's long-term security interests.

Israel, meanwhile, wants Syria to distance itself from Iran and Hezbollah but remains cautious about the emergence of a stronger Syrian state operating under significant Turkish influence along its northern border.

Trump's pledge to remove Syria from the U.S. list of state sponsors of terrorism represents more than another stage in easing sanctions.

The move would fundamentally alter Syria's legal and political standing within the U.S. system. While sanctions relief primarily expands economic opportunities, removal from the terrorism list would also affect foreign assistance, international banking, defense exports, foreign investment and Syria's reintegration into global diplomatic and financial institutions.

The decision, however, is not immediately effective.

Trump has formally notified Congress, triggering a mandatory 45-day review period during which lawmakers can examine the administration's decision.

That review process elevated the importance of al-Sharaa's meeting with a congressional delegation, making it arguably more consequential than his brief public appearance alongside Trump.

While Trump outlined the administration's political direction, Congress retains the authority to either reinforce the policy or impose additional conditions.

U.S. Special Envoy for Syria and Iraq Tom Barrack described the congressional discussions as a "high-level, pivotal" meeting that marked the beginning of "a new chapter" in U.S.-Syrian relations.

Barrack said Washington and Damascus share growing strategic interests and described Syria as central to the future of the Middle East.

His remarks reflected what appears to be a bipartisan consensus in Washington, even as members of Congress focused on conditions surrounding the U.S. opening toward Syria, including counterterrorism cooperation, foreign fighters, Syria's ties with Russia and Iran, Israel's security and developments in neighboring Lebanon.

One of the clearest indications of Washington's expectations emerged during discussions about Lebanon and Hezbollah.

Asked publicly whether Syria could help address the Hezbollah issue, Trump replied that "the Syrians can help" and said the situation would become clearer over time.

The comment appeared less forceful than previous remarks in which Trump suggested Syria should "deal with" Hezbollah directly, but it nevertheless signaled that Washington sees a potential role for Damascus.

The most revealing comments came later aboard Air Force One.

Trump disclosed that al-Sharaa had given him "commitments" regarding Hezbollah, although he declined to elaborate on their content.

That statement suggested the relationship has progressed beyond general discussions toward undisclosed security understandings.

The emerging picture points to a public U.S. incentive—removing Syria's terrorism designation and advancing sanctions relief—in exchange for security commitments that remain confidential, particularly regarding Lebanon, one of the region's most sensitive files.

Even so, Trump's remarks do not necessarily indicate that Syria is preparing to intervene militarily in Lebanon.

Such a move would carry significant political and security costs for both countries and could ignite tensions that Turkey has little interest in encouraging.

Instead, analysts say the comments raise the possibility of a more coordinated Syrian role, the scope of which will likely depend on future regional developments.

While the United States, Turkey and Israel all seek to curb Iranian influence, they differ over how Syria should contribute to that objective.

Washington hopes Damascus can help weaken Hezbollah by disrupting Iranian supply routes, combating weapons smuggling and reducing Tehran's regional influence.

Israel shares the goal of pushing Iran and Hezbollah away from both Syria and Lebanon but remains reluctant to see a strong Syrian government emerge under Turkish protection.

Turkey, meanwhile, seeks to reduce Iran's influence inside Syria while preserving regional stability.

Ankara opposes turning Syria into a platform for confronting Hezbollah inside Lebanon or allowing Syrian territory to become another arena for direct confrontation between Israel and the Iran-backed axis.

Israel's role in shaping Washington's approach was evident during one of the most sensitive moments of the meetings, when Trump, standing alongside al-Sharaa, emphasized that he had done more for Israel than any previous U.S. president, citing his recognition of Jerusalem as Israel's capital and Israeli sovereignty over the Golan Heights.

The remarks served as a reminder that Washington's rapprochement with Damascus remains closely tied to Israeli strategic interests.

Al-Sharaa returned from Ankara having secured a major diplomatic breakthrough, but one accompanied by significant new obligations.

The United States has opened the door to a broader relationship with Damascus while preserving the ability—through both the White House and Congress—to shape the pace and conditions of that engagement.

Turkey has reinforced its role as Syria's principal gateway to the West while ensuring Damascus remains within its sphere of influence.

At the same time, Israel continues to define many of the strategic boundaries of U.S. policy toward Syria.

As Washington offers public incentives through sanctions relief and the removal of Syria's terrorism designation, questions remain over the undisclosed security commitments expected from Damascus.

Those commitments, particularly regarding Hezbollah and Lebanon, are likely to determine whether the current diplomatic opening develops into a lasting realignment of Syria's place in the regional order.
