This marked the collapse of a decade-long diplomatic agreement that once promised to restrain Iran’s nuclear program in exchange for sanctions relief. The re-imposition of UN sanctions on Iran through the JCPOA snapback mechanism underscores not only Iran’s isolation, but also the failure of Western diplomacy. By abandoning reciprocity, relying on coercion, and aligning with Washington’s “maximum pressure” strategy, European powers not only eroded trust but also exposed their inability to sustain credible agreements, making sanctions a symbol of diplomatic defeat rather than success.

The roots of Iran’s sanctions regime date back to 2005 when the International Atomic Energy Agency (IAEA) declared Iran non-compliant with its safeguard obligations. In 2006, the UN Security Council unanimously approved sanctions restricting uranium enrichment materials, missile technology, and related financial transactions. Successive resolutions in 2007 and 2008 further tightened the restrictions. In 2010, sanctions were expanded to target Iran’s oil revenues and banking sector, linking them directly to proliferation concerns.

These sanctions were lifted under the JCPOA in 2015, an agreement between Iran and world powers. The agreement also included a snapback clause; if Iran violated its obligations, any party to the agreement can activate the snapback mechanism and re-impose sanctions before the expiration date of the JCPOA on October 18, 2025. On August 28, 2025, after repeatedly accusing Iran of non-compliance, the E3 (France, Germany, and the UK) activated the snapback mechanism that will re-impose UNSC sanctions on Iran after a 30-day time period.

The snapback that went into effect on September 28, 2025, reinstates UNSC sanctions, originally imposed 2006–2010. These sanctions include an arms embargo, ban on ballistic missile technology transfers, and restrictions on oil revenues and financial services—including Iran’s central bank. This decision aligns Europe more closely with the American position, despite Washington having withdrawn from the JCPOA in 2018. However, the sanctions are not binding on China and Russia, and both remain aligned with Iran and critical of the European move.

Iranian President Masoud Pezeshkian condemned the sanctions as “unfair, unjust, and illegal.” Tehran recalled its ambassadors from the United Kingdom, France, and Germany for consultations but clarified it had no immediate plans to withdraw from the Nuclear Non-Proliferation Treaty (NPT). Any further response, however, will likely be determined by the Iranian parliament.

The JCPOA was built on reciprocity and trust, but after the US withdrew, Europe failed to deliver promised economic benefits. Instead, Iran faced escalating accusations and even sabotage.

Coordinated attacks by the US and Israel in June 2025 on Iran’s nuclear facilities during negotiations eroded any remaining trust in Western intentions. Today, Iranian officials view Western diplomacy less as a pathway to compromise and more as a tool for coercion and deception.

While Russia and China echoed Iran’s position and warned that the European move would fuel further instability in the region, the E3 maintained that Iran’s nuclear activity crossed red lines. E3 members also emphasized that diplomacy was not over by offering to delay sanctions for six months if Iran restored access for inspectors and engaged in talks with the US.

The reactivation of sanctions primarily reflects Europe’s failure to secure diplomatic gains after the 12-day war earlier this year. Western powers assumed Iran’s weakened position, given that internal unrest, economic strain, and military pressure would push it toward compromise. Instead, Iran resisted demands for zero enrichment and even presented partial solutions at the UN, which were rejected. The E3’s alignment with Washington now resembles Trump’s “maximum pressure” strategy, raising the risk of further escalation rather than resolution.

Nevertheless, the first brunt of these sanctions will fall on ordinary Iranians. Currency devaluation, unemployment, and economic stagnation will intensify along with the hardships caused by protests and war. The Iranian banking sector, already fragile, faces further isolation. Yet for Iran’s leadership, these sanctions may not dramatically alter strategic calculations. Having endured American sanctions since 2018, Tehran has adapted by relying increasingly on its Look East strategy to deepen economic and diplomatic ties with China and Russia.

The energy sector will again come under strain, but much depends on how aggressively the US enforces secondary sanctions, particularly against China, one of Iran’s largest oil buyers. If oil exports continue through alternative routes, Iran will remain financially afloat, albeit constrained. Thus, the sanctions are more likely to weaken Iran internally while leaving its external policies largely intact.

Perhaps the most dangerous consequence of the snapback is the possibility of renewed Israeli strikes against Iran’s nuclear infrastructure. In June 2025, Israel used IAEA findings as justification for bombing Iranian facilities, sparking a costly 12-day conflict. Israel could again resume attack under the guise of re-imposition of UNSC sanctions.

The attacks stalled Iran’s nuclear program by roughly two years, thus dragging the US into a wider regional confrontation with little strategic gain. By contrast, the JCPOA achieved restrictions on Iran’s nuclear program without military confrontation and provided economic benefits and political openings for both sides. It shows that diplomacy slows proliferation more effectively and cheaply than war. Yet with sanctions restored, Israel may once again seek a military solution, raising the risk of escalation across the region.

The re-imposition of UN sanctions through the snapback mechanism signals both the collapse of trust in the JCPOA framework and the deepening rift between Iran and the West. For Iran, the sanctions reinforce the perception that Western promises are unreliable, and diplomacy is a trap.

For Europe, the move highlights its limited influence, as it increasingly gravitates toward Washington’s approach rather than pursuing independent solutions. Ultimately, sanctions will punish ordinary Iranians more than they will alter Tehran’s strategic direction. With China and Russia unlikely to comply, Iran’s external lifelines remain intact. What has been lost, however, is the fragile trust built over a decade of negotiations.

The JCPOA demonstrated that diplomacy could restrain Iran’s nuclear ambitions without war; the snapback demonstrates how easily that progress is undone. As tensions rise, the international community faces a choice, either double down on coercion or return to diplomacy. The lesson of the past decade is unmistakable: military and economic pressure may delay Iran’s nuclear program, but only diplomacy can stop it.

Snapback Sanctions: The Collapse of Western Diplomacy with Iran was originally published on Global Security Review.

Considering several key factors, including KSA’s concerns and evolving security calculus in Syria post-Assad, as well as the growing competition with Iran, Turkey, and Israel, Riyadh’s multidimensional approach to turning Syria from a threat zone into a buffer state can be highlighted, where it can be assumed that in the eyes of Saudi policymakers, Syria today is not just a crisis—it is a frontline of national defense.

A Post-Assad Vacuum and Saudi Strategic Anxiety

The collapse of the Assad regime, though celebrated in some Arab capitals as the end of a brutal era, has opened a power vacuum in Damascus that threatens to unleash a new phase of instability. For KSA, this vacuum is not just a theoretical concern—it is a real-time geostrategic challenge. The kingdom’s national security architecture is heavily shaped by two core threats emanating from northern Arab lands: the spread of Iranian proxies and the return of extremist networks exploiting failed governance. Syria, with its shattered institutions, porous borders, and competing militias, presents both.

The memory of Iraq’s fragmentation after 2003 lingers heavily. Riyadh understands that when Arab state sovereignty collapses, the resulting anarchy can cross borders. KSA’s southern security challenges in Yemen are still active; to see a similar threat emerge from the north would overstretch its security posture. Thus, Syria has become a high-stakes arena—one that Riyadh cannot afford to ignore.

Competing Powers in Syria’s New Chessboard

Iran: A Threat Undiminished

Despite Assad’s downfall and the recent tactical retreats of Iranian-aligned forces, Tehran is not likely to withdraw easily. On the contrary, it is adapting. Iranian-backed militias, particularly in southern Syria and the Qalamoun region, will likely continue to consolidate control over trade routes and urban districts under the guise of local tribes and militias. In this regard, Tehran’s objectives are threefold. Firstly, it aims to maintain influence in the Levant through non-state actors. Secondly, it seeks to sustain a logistics corridor linking Iran to Lebanon via Iraq and Syria. Furthermore, expanding its asymmetric capabilities—such as drone operations and Captagon trafficking—to destabilize adversaries indirectly remains to be among Iran’s objectives.

Riyadh sees the situation for what it is: a long-term entrenchment strategy. Iranian influence in Syria is no longer contingent on the Assad regime’s survival; it is embedded in paramilitary networks, ideological infrastructure, and narco-trafficking cartels. The proliferation of Captagon—a synthetic drug smuggled extensively into Saudi Arabia—has already become a national crisis. It is both a public health threat and a political signal from Iran: proxy warfare can take many forms.

Turkey: Strategic Expansionism in the North

While Turkey’s military presence in northern Syria is largely framed as an anti-Kurdish campaign, its ambitions extend further. Ankara has built governance mechanisms, school education systems, police units, and currency networks (using the Turkish lira) across key zones from Afrin to Jarabulus.

Saudi Arabia is concerned about Turkey’s influence on multiple fronts. On one hand, it supports factions influenced by the Muslim Brotherhood, which Riyadh opposes ideologically. In addition, it presents an alternative Sunni leadership model in the region, weakening Saudi Arabia’s position of being the central voice of Sunni politics. On the other hand, it fragments Syria’s territorial integrity, which undermines efforts to rebuild a centralized Arab-led post-conflict state.

Though tensions between Riyadh and Ankara have eased recently, especially post-2021 diplomatic resets, deep-seated rivalry remains. Syria is where that rivalry plays out subtly—through reconstruction bids, tribal influence, and diplomatic patronage.

Israel: Security-Driven Fragmentation

Israel’s posture in Syria is surgical, not expansive—but it is no less consequential. Through persistent airstrikes targeting Iranian and Hezbollah assets, covert liaisons with Druze militias in Suwayda, and alleged backing of anti-Iran groups in southern Syria, Israel is carving out spheres of strong influence.

While KSA shares Israel’s concerns over Iranian militarization, it is wary of the side effects. Israel’s support for minority autonomy (especially the Druze) or indirect fragmentation of Syria risks turning the country into a loose collection of zones governed by foreign interests. For Riyadh, the fragmentation of Syria not only endangers Arab unity—it opens space for criminal syndicates, extremist revival, and ideological confusion that could destabilize Jordan and, by extension, Saudi Arabia’s northern frontier.

Riyadh’s Multi-layered Response: From Passive Diplomacy to Strategic Projection

Faced with this hostile mosaic of actors, KSA is executing a comprehensive policy in Syria that mixes security, economics, diplomacy, and media influence.

1. Hard Security: Countering Extremism and Trafficking

Saudi security agencies are likely to expand coordination with Jordan and Iraq to monitor cross-border infiltration and drug routes. The Captagon crisis has led Riyadh to treat Syrian drug trafficking not merely as criminal activity, but as hybrid warfare. Defensive fortifications, signal intelligence operations, and counter-smuggling raids are being intensified along the northern corridor.

Simultaneously, Riyadh is likely to be tracking the resurgence of ISIS remnants in eastern Syria. It is likely investing in tribal militias and vetted opposition units capable of neutralizing terrorist footholds without creating long-term militias that could evolve into new threats.

2. Economic Leverage: Buying Strategic Influence

Saudi Arabia’s pivot to reconstruction diplomacy is both humanitarian and strategic. By calling for sanctions relief, Riyadh aims to reduce Syria’s reliance on Iran and Russia and reintegrate it into the Arab economic order. Saudi intent in paying Syria’s debt to the world bank as well as possible strategic investments in infrastructure, energy, and services—particularly in Sunni-majority urban centers like Aleppo and Daraa—is intended to build loyalty and dependency.

Moreover, the Kingdom is leveraging sovereign funds and private sector tools to position itself as Syria’s main Arab partner in the post-war phase. It wants to ensure that the rebuilding of Syria does not become a Turkish or Iranian-led project.

An Evolving Alignment with Turkey: Tactical Convergence

Ironically, Syria is also offering Saudi Arabia and Turkey an opportunity for pragmatic convergence. While mutual distrust remains, both states share certain interests. This includes preventing full Iranian dominance, keeping extremist groups marginalized, and rebuilding economic influence in Syria to offset Western retreat.

This has possibly opened a window for joint intelligence sharing and perhaps coordinated reconstruction projects, especially in areas where Sunni communities dominate. For Riyadh, this is most likely not an alliance but a temporary alignment of interests that must be carefully managed.

Supporting Syria’s Transitional Government: A Bid for Arab Sovereignty

Perhaps most crucially, KSA is throwing its weight behind the Syrian transitional government emerging from the post-Assad political framework. Riyadh’s objectives are clear, and these are to reunify Syria under an Arab-oriented administration, prevent federalization or sectarian fragmentation, and, most importantly, marginalize Iranian-aligned or extremist political actors.

Backed by Gulf states, this new Syrian leadership is presumably envisioned as a technocratic, security-minded, and pro-Sunni Arab entity unlike the Assad regime which was viewed as a pro-Iranian. Saudi Arabia’s goal is not to install a puppet but to ensure that the new government aligns with regional stability, Arab League integration, and mutual security commitments.

Syria as a Forward Defense Zone

Saudi Arabia’s posture toward Syria has shifted dramatically—from cautious observation to assertive engagement. The kingdom is likely to be treating Syria not only as a humanitarian concern but as a critical northern front for its long-term security. It is investing in hard power, economic influence, and regional diplomacy to shape Syria’s post-conflict architecture.

In doing so, Riyadh is acknowledging a broader regional truth: the fate of failed or transitioning Arab states cannot be left to the mercy of non-Arab powers, including Iran, Russia, Turkey, and Israel. From Damascus to Daraa, Syria is no longer a distant conflict—it is a forward defense zone for Saudi Arabia’s territorial integrity, generational stability, and regional leadership. However, the challenge ahead lies in sustaining this engagement without overreach, balancing power projection with local legitimacy, and ensuring that Saudi Arabia’s Syria policy remains strategic—not reactive.

Syria and Saudi Arabia’s Northern Front: A New Theatre for the Kingdom’s Security Policy was originally published on Global Security Review.

In 2018, President Donald Trump withdrew from the JCPOA, the nuclear agreement brokered by President Barack Obama in 2015, as it “failed to protect America’s national security interests.” Trump justified his withdrawal by arguing that the agreement, as “a windfall of cash”, did not curbed Iran’s malign activities. Instead, he contended, it provided financial resources that “enriched the Iranian regime and enabled its malign behavior.”

For Iran’s non-Persian national and ethnic groups, the failure of the JCPOA was also due to its disregard for human rights and domestic oppression. Western negotiators prioritized nuclear and missiles restrictions and regional security while sidelining the people’s suffering under an authoritarian regime. The economic relief from the deal landed in the hands of regime elites, particularly the Islamic Revolutionary Guard Corps (IRGC) and their affiliates. Ordinary peoples saw little benefit. Instead, the regime doubled down on its crackdown against marginalized groups, including Kurds, Baloch, and Arabs. With reduced external pressure, Tehran felt emboldened to impose its Persian-Shia ideological hegemony even more aggressively.

Now, with talks of a renewed deal resurfacing, one must ask: will this agreement, like its predecessor, serve only the regime’s interests? Trump’s letter outlined conditions for sanctions relief, including an end to Iran’s nuclear weapons program, cessation of uranium enrichment, ceasing financial support to Hezbollah and halting arms transfers to the Houthis, and dismantling its militias in Iraq. However, these terms, like before, fail to address the human rights abuses within Iran. If a future deal ignores these realities, it will once again be the oppressed groups who pay the price.

The absence of human rights considerations in Western negotiations with Iran is not incidental—it is a consistent pattern. Historically, the West has often prioritized short-term strategic gains over the long-term aspirations of the people in Iran. The result has been a cycle of diplomatic engagements that empower the ruling elite while leaving everyday people in a deepening state of economic hardship and political repression. Sanctions relief, while theoretically aimed at improving the people’s economy, has instead served as a financial injection for the regime’s military-industrial complex, allowing it to tighten its grip on power.

For Iran’s diverse population—comprising Baluchis, Kurds, Armenians, Qashqais, Azeris, Arabs, Turkmens, Gilakis, Tabaris, Talyshis, and religious groups including Jews and Bahais—a nuclear deal that fails to address their plight could be devastating. The regime’s persecution of non-Persian groups has been marked by disproportionate executions of Kurds and Baluchis, arbitrary detentions, and systematic cultural suppression. Economic marginalization has left these groups disproportionately affected by unemployment, poverty, and lack of access to basic services. A deal that does not explicitly condition sanctions relief on improvements in human rights will serve as yet another tool for the government to sustain its policies of repression and forced assimilation. Moreover, the suppression of dissent extends to students, journalists, and activists who have faced severe crackdowns for expressing opposition to the regime’s policies.

This regime operates outside conventional norms, yet Western commentators in mainstream media, instead of acknowledging the ideological and religious motives of Iran’s Shi’ite rulers, continue to search for rational justifications that overlook the regime’s true nature. If the past is any indication, a nuclear deal without guarantees for the people of Iran will reinforce the status quo: economic benefits funneled to regime elites, intensified repression of national and ethnic minorities, and continued expansion of Iran’s regional influence at the expense of its citizens. A more “comprehensive” approach to diplomacy with Iran must incorporate human rights as a core negotiating principle. Strict oversight and accountability measures must be implemented to prevent state-controlled entities, such as the judiciary, from imposing verdicts on the people, and the IRGC from monopolizing financial resources and oppressing dissidents. Furthermore, human rights organizations and genuine opposition figures should have a voice in shaping the terms of any agreement.

Ultimately, the goal of any nuclear deal should also aim to create conditions that empower its people to pursue democratic aspirations. A policy that prioritizes human rights alongside the security of Israel and the US would be strategically effective in fostering long-term stability in the region.
