Iran’s internal political and factional divisions are likely to fundamentally reshape the country’s foreign policy posture across the Middle East, potentially disrupting longstanding alliances and creating new openings for diplomatic realignment. The struggle between hardline conservatives and reformist factions over Iran’s economic future, nuclear program stance, and regional military engagement is deepening precisely at a moment when regional powers are recalculating their own strategic positions—making Iran’s internal trajectory a central variable in whether the Middle East stabilizes or fractures further. When Supreme Leader Khamenei’s hardline supporters gained ground over reformists following the disputed 2024 presidential succession and escalating economic pressures, it signaled that Iran will likely pursue more confrontational regional policies, potentially driving Gulf states closer to the United States and Israel while pushing Iran deeper into dependence on Russia and China.
The core question is not whether Iran will change course, but whether its internal divisions will create enough policy chaos to force its current allies to seek alternative partnerships. Iran’s brutal suppression of domestic dissent, its continued pursuit of nuclear capabilities despite international sanctions, and the factional infighting over economic reform all point toward a more isolated Iran that cannot sustain its previous regional role through traditional diplomacy. This isolation will reshape the entire balance of power in the Middle East, forcing countries like Iraq, Syria, and Lebanon to reconsider their reliance on Iranian military and political support.

How Do Iran’s Internal Factional Battles Shape Foreign Policy?
iran‘s government is not a monolith but rather an arena of competing power centers: the Supreme Leader’s office, the Revolutionary Guards (IRGC), the Foreign Ministry, and networks of hardline ideologues who view regional dominance as existential to Iran’s survival. These factions have fundamentally different visions of how Iran should operate internationally. The hardliners, who control the IRGC and much of the intelligence apparatus, advocate for aggressive confrontation with the United States and Israel, proxy warfare through groups like Hezbollah and militia forces in Iraq, and deepening ties with Russia and China as counterweights to Western pressure. Meanwhile, the now-weakened reformist faction argued for nuclear negotiations, sanctions relief, and normalized relations that could have opened Iran to international investment and reduced its need for costly regional military commitments. The 2024 power consolidation by hardliners effectively ended any near-term possibility of Iran moderating its foreign policy.
The IRGC, which operates semi-independently from civilian government and controls vast economic interests through its Quds Force and affiliated companies, expanded its influence over key policy decisions. This matters concretely: when the IRGC dominates policy, Iran tends to prioritize funding proxy militias in Iraq and Syria over domestic infrastructure investment, diverting scarce resources away from an economy already ravaged by sanctions. The comparison is instructive—during the Rouhani presidency (2013-2021), Iran negotiated the Joint Comprehensive Plan of Action (JCPOA), which temporarily limited its nuclear program in exchange for sanctions relief. That reformist approach led to measurable economic gains and reduced regional military spending. The current hardline ascendancy has reversed this calculation entirely.
The Economic Crisis Driving Geopolitical Desperation
Iran’s economy is in genuine crisis, and this constraint is reshaping its alliance options in ways that previous analysts underestimated. The Iranian currency (the rial) has lost roughly 90% of its value over the past decade, inflation routinely exceeds 40% annually, youth unemployment hovers around 30%, and foreign currency reserves remain depleted despite recent modest inflows from limited oil sales. This economic deterioration is not an accidental byproduct of Trump-era sanctions and international isolation—it is a direct consequence of Iran’s own policy choices, particularly its refusal to comply with the JCPOA and its continued pursuit of regional military adventures that consume billions of dollars annually. What makes this limitation critical is that Iran can no longer afford to simultaneously maintain its current alliance structure and pursue domestic economic recovery.
The regime must choose between funding the IRGC’s proxy networks across Iraq, Syria, Lebanon, and Yemen—which costs an estimated $10-15 billion annually—or investing in basic economic stabilization. It cannot do both. This constraint is already forcing tactical changes: Iran has been pulling back from some commitments in Syria and Iraq not out of strategic choice but out of financial exhaustion. The regime is attempting to offload some military costs onto Russia (which provides weaponry and logistical support) and China (which provides financial lifelines and sanctions-busting trade), but these partners have shown little willingness to subsidize Iran’s entire regional military apparatus. This dependency creates leverage that neither Russia nor China possessed before, fundamentally altering the nature of Iranian alliances from partnerships between equals to relationships of subordination.
Regional Realignment: How Gulf States and Israel Are Responding
The Abraham Accords of 2020, which normalized relations between Israel and several Gulf Arab states, have created an entirely new dynamic that Iran’s internal crisis is amplifying rather than restraining. The United Arab Emirates, Bahrain, Sudan, and Morocco all moved toward diplomatic recognition of Israel, and while this was primarily driven by shared concerns about Iran, the acceleration of Iran’s economic and political crisis has emboldened these countries to accelerate their ties with Israel and the United States. Saudi Arabia, which continues to maintain nominal hostility toward Israel while simultaneously coordinating military and intelligence operations, has been notably cool toward Iranian overtures for regional dialogue despite previous diplomatic engagement brokered by China. The warning here is crucial: Iran’s internal paralysis is not creating space for diplomatic resolution but rather enabling a coalition of states to isolate Iran further without fear of effective retaliation.
When Iran is consumed with internal factional struggles, it has less capacity to negotiate meaningfully with Saudi Arabia or to exploit divisions within the Gulf Cooperation Council. The UAE has capitalized on this moment to deepen energy and defense partnerships with the United States, position itself as a tech hub independent of Iranian influence, and strengthen intelligence sharing with Israel regarding Iranian military capabilities and proxy networks. Kuwait and Qatar, which have historically maintained more balanced relationships between Iran and the Gulf monarchies, are being forced to choose sides as Iran’s crisis deepens. This is not a equilibrium—it is a strategic defeat for Iran that may take years to reverse even if internal political conditions improve.
The Trump Administration Factor: How U.S. Policy Amplifies Internal Iranian Divisions
The trump administration’s “maximum pressure” campaign—characterized by the withdrawal from the JCPOA in 2018, reimposition of comprehensive sanctions, and military threats—has directly strengthened the hand of Iran’s hardline faction by validating their argument that engagement with the West is futile. This is the paradox: Trump’s confrontational approach, which was designed to force Iran toward capitulation, instead entrenched the very hardline ideologues who oppose any compromise with the West. The reformists, who had argued that sanctions relief through negotiation was achievable, lost credibility when the Trump administration tore up the nuclear deal unilaterally. The Trump administration’s return to power in 2025 has intensified this dynamic further.
Expanded sanctions targeting Iran’s remaining oil exports, new restrictions on Iranian financial institutions, and increased military presence in the Persian Gulf have pushed Iran’s decision-makers toward even greater dependence on Russia and China while simultaneously reducing their capacity to fund regional proxies at previous levels. However, the constraint here is that Trump’s pressure, while economically devastating, has not produced the policy concessions the administration seeks. Instead, it has simply reduced Iran’s options while making the hardliners more entrenched—creating a situation where Iran becomes more desperate and potentially more unpredictable in its regional military activities precisely when the United States is attempting to contain it. The comparison with Cold War containment is apt but imperfect: the Soviet Union had greater economic capacity to sustain its alliances, whereas Iran is rapidly burning through reserves and facing the real possibility of state capacity collapse in some regions, particularly if Iraq or Syria experiences further destabilization.
Hezbollah, the Militias, and the Proxy Network Under Strain
Iran’s regional influence fundamentally depends on its ability to fund and coordinate proxy forces: Hezbollah in Lebanon, various militia groups in Iraq (the Popular Mobilization Forces), the Houthis in Yemen, and Palestinian resistance groups. These organizations receive an estimated $700 million to $1 billion annually in direct Iranian funding, training, weapons, and intelligence support. But Iran’s economic crisis is forcing difficult choices about which proxies to prioritize and which to allow to degrade. The warning here is stark: as Iran reduces funding to these groups, they do not disappear—they fragment, become more autonomous, and sometimes turn to other revenue sources including organized crime, which destabilizes the regions where they operate. Hezbollah, historically Iran’s most capable and politically sophisticated proxy, is already under intense pressure from multiple directions: Israeli military strikes against Iranian military advisors and weapons shipments in Syria, reduced Iranian funding flows, internal Lebanese political fragmentation that limits Hezbollah’s freedom of action, and international efforts to designate its financial networks.
The organization remains formidable, but the limitation is obvious: Hezbollah cannot simultaneously fight Israel, maintain political legitimacy in Lebanon, and survive on declining Iranian funding without making difficult tradeoffs. In Iraq, the situation is worse. The Popular Mobilization Forces, which were created and funded by Iran to counter ISIS, have become semi-autonomous power centers that actually compete with Iran for influence and revenue. As Iranian funding declines, these groups have turned to extortion, smuggling, and political predation that destabilizes Iraqi state institutions. Iran created these instruments of regional power, but they are increasingly beyond Tehran’s ability to control or sustainably fund.
Russia and China: New Alliance Dynamics or Strategic Entrapment?
Iran’s deepening economic crisis has pushed it toward greater reliance on Russia and China, but these relationships contain fundamental asymmetries that favor the external powers. Russia, facing its own economic isolation over Ukraine, views Iran as a potential military supplier, a source of drone and missile technology, and a way to complicate American regional strategy. China views Iran primarily as an energy supplier and a counterweight to American hegemony, but has shown little willingness to fundamentally restructure its relationship with the United States on Iran’s behalf. The China-Iran Comprehensive Strategic Partnership, signed in 2021 and expanded in 2024, commits China to long-term investment in Iranian energy and infrastructure—but at terms highly favorable to China, with security provisions that subordinate Iranian interests to Chinese strategic objectives. A specific example illustrates the problem: Chinese companies have negotiated to develop Iranian oil fields at reduced rates in exchange for currency and infrastructure investment, but these agreements explicitly exclude Chinese support for Iran’s military nuclear program or proxy networks.
China will provide a financial lifeline, but not the kind of strategic partnership that Iran needs to maintain regional dominance. Russia is similarly constrained by its own resource limitations and inability to project sustained power across the Middle East. Neither Russia nor China can replicate the role that a healthy Iranian economy could fund independently. This creates a trap: Iran becomes more dependent on these powers while simultaneously losing the autonomy to pursue regional policies that actually serve Iranian interests. The lesson from other sanctions-crippled states like Syria and Venezuela is that this dependency often becomes permanent, as regimes lose the capacity to build independent power bases and instead become locked into relationships with external patrons who can withdraw support at will.
Future Trajectories and the Possibility of Regional Instability
The coming years will likely see Iran pursuing one of two broad strategies, each with distinct implications for Middle East stability. The hardline faction may attempt to compensate for economic weakness through asymmetric warfare—increased drone and missile attacks on shipping, cyberattacks on critical infrastructure, and intensified support for proxy forces in high-value targets like Iraq and Syria. This strategy is attractive because it requires minimal funding and maximum symbolic impact, but it risks triggering military escalation that Iran cannot sustain if the United States or Israel responds with sustained campaigns. The alternative is grudging acceptance of Iran’s reduced regional role, withdrawal from the most expensive commitments (particularly Syria), and a focus on consolidating power at home—but this requires the hardline faction to admit strategic defeat, which is politically impossible given how deeply they have staked their legitimacy on regional dominance.
The most likely outcome is an extended period of Iranian instability masked by aggressive external rhetoric, with periodic crises triggered by miscalculation or deliberate escalation attempts. The Middle East’s future depends significantly on whether external powers (the United States, Russia, China, and Gulf states) allow this period of Iranian internal crisis to produce a new regional equilibrium through negotiation, or whether competition over Iran’s future becomes yet another theater for great power conflict. The Trump administration’s current approach—maximum pressure without negotiation off-ramps—pushes toward the latter scenario. If Iran’s economy continues to deteriorate without relief mechanisms, the regime may face internal collapse or revolutionary upheaval that destabilizes not just Iran but its neighbors across Iraq, Syria, and the Persian Gulf. Alternatively, sustained engagement from regional powers and a modulation of sanctions pressure could allow Iran’s eventual economic recovery and a more rational regional role—but this requires a deliberate policy shift that seems unlikely given current geopolitical alignment.
Conclusion
Iran’s internal conflict between hardliners and reformists is reshaping Middle East alliances because it has eliminated Iran’s capacity to pursue sophisticated, sustainable regional strategy and forced the country into tactical desperation and great power dependency. The economic crisis underlying these political divisions is not temporary or reversible through minor policy adjustments—it reflects fundamental unsustainability in Iran’s current model, which tries to simultaneously maintain a costly regional military apparatus, develop nuclear weapons, fund proxy networks, and suppress domestic dissent on a shrinking economic base. As Iran’s internal crisis deepens, its former allies are recalibrating their own partnerships, the Gulf states and Israel are consolidating their alignment against Iran, and new powers like Russia and China are positioning themselves to extract maximum advantage from Iranian desperation.
The practical implication for American policy and international observers is that Iran’s challenge to regional stability is likely to intensify rather than moderate in the near term, even as Iran’s capacity to sustain that challenge is declining. This paradox—of a weaker Iran attempting more aggressive behavior—suggests a period of heightened instability, with the outcome dependent on whether the international community can manage the transition toward a new regional equilibrium or whether competition over Iran’s future produces escalation and conflict. Monitoring factional dynamics within Iran’s leadership, tracking changes in IRGC resource allocation, and observing shifts in Iran’s funding for proxy networks will be critical indicators of whether the regime is moving toward confrontation or eventual accommodation with its regional rivals.
