The ongoing conflict between Israel and Iran in June 2025 marks a pivotal moment in Middle Eastern geopolitics. This analysis explores the optimal scenario—one involving a U.S.-backed regime change in Iran—and its profound implications for regional security architecture, global energy markets, trade, and the strategic balance among great powers. Grounded in current military developments, diplomatic shifts, and regional realignments, this assessment traces a realistic path toward the emergence of a moderate Iranian government, renewed regional cooperation, and the weakening of the revisionist Eurasian axis.

From Proxy War to Open Confrontation

The eruption of war between Israel and Iran arises from a complex nexus of ideological antagonism, regional power rivalries, and global struggles for influence in the Middle East. Since the 1979 Islamic Revolution, Iran’s theocratic regime —upheld by the Islamic Revolutionary Guard Corps (IRGC)— has sought to impose its regional dominance through asymmetric warfare and strategic alliances, primarily by supporting armed groups hostile to Israel and the United States. Israel, by contrast, has sought to secure regional dominance in response to what it has perceived as an existential threat since its founding in 1948.

The escalation following October 7, 2023, though destabilizing, created an opening for the reconfiguration of regional power. One scenario envisions the collapse of Iran’s militarized theocracy and the emergence of a pro-Western government. Such a transition —orchestrated through targeted U.S.-Israeli operations— and Iran’s gradual reintegration into the international system, would not only represent a historic victory for Israel but also redefine the strategic architecture of Middle Eastern security.

Dismantling Iran’s hardline leadership and incrementally integrating the country into a Western-aligned security framework could significantly weaken the Eurasian bloc, depriving China and Russia of a key regional partner and complicating their strategic calculus.

The final phase of the conflict, marked by a coordinated assault on Iran including operations from within its borders, involved intensive aerial strikes leveraging air superiority and advanced technologies and methods —particularly drone systems that neutralized the country’s air defense network. The attacks targeted military infrastructure and leadership nodes across all branches of Iran’s armed forces (Islamic Republic of Iran Armed Forces, IRGC, Quds Force), nuclear facilities, scientific laboratories, airports, missile launch sites, as well as governmental and energy installations. The resulting degradation of military capability and disruption of the regime’s hierarchical command structure triggered internal instability and prevented an immediate response, opening a rare window of opportunity for potential reform or even regime change.

Regime Change and Power Transition in Iran

The dismantling of Iran’s military leadership, along with the targeting of its top nuclear scientists, constituted the core of Israel’s strategic objectives. For Washington, the strikes against Iran’s hardline regime opened a unique window of opportunity for intervention aimed at a managed power transition—avoiding the chaos and power vacuums that have often followed regime collapses in the Middle East, such as the rise of extremist groups like ISIS in Iraq and Syria. The restoration of the Pahlavi monarchy was among the scenarios considered during the 12-day Israel–Iran war, though many voiced concerns about potential secessionist movements, internal political fragmentation, and the risk of armed uprisings.

The U.S. strategic bombing campaign, which culminated in a ceasefire publicly announced on social media by the U.S. President, clearly demonstrated Washington’s intent to end the conflict on terms aligned with long-term U.S. interests—while also reinforcing Israel, which had suffered significant damage from Iranian strikes. Neutralizing Iran’s nuclear program, however, would not merely eliminate an immediate threat; it could serve as the first decisive step toward reshaping the region’s broader geopolitical reality.

In this scenario for the West—particularly for the United States and Israel—the destabilization that would likely follow precise military strikes must be addressed with resolve. Either the Iranian regime complies, altering its strategic and foreign policy in alignment with Washington, or it must be replaced. A return to the Pahlavi monarchy, although tested in the past, is unlikely to gain domestic legitimacy from a population that once revolted to overthrow it. A third, more viable option could involve the formation of an alternative Muslim-led leadership structure, comprising moderate, pro-Western elements from within the current elite.

The encouraging of protests and civil unrest—something that Israel could support through its networks inside Iran—would widen internal cracks within the regime. A potential resignation by Supreme Leader Ali Khamenei (a possible exit strategy for the regime in the face of defeat) would create a historic opportunity for a carefully managed transfer of power, avoiding the emergence of yet another source of regional instability.

The assassination of Khamenei, operationally difficult and of uncertain outcome, would more likely produce the opposite effect —rallying the population and power structures around the regime— and is therefore a strategically flawed option. The United States must choose between maintaining a dangerous Iran at the core of the Eurasian strategic alignment —a future threat to broader Western geopolitical interests— or facilitating the emergence of a pro-Western Iran, something that a portion of its population may be willing to support, at least partially.

Even in the case of a temporary retreat by the current leadership —an outcome that remains unlikely— the United States must project itself as a stabilizing force, not an occupying one, to avoid becoming entangled in the harsh topography and nationalist sentiment embedded in Iran’s mountainous terrain.

Acting as a guarantor of internal stability during a transition to a reformist Iran —without repeating the mistakes of past interventions— the United States could bring Iran closer to Israel and key Gulf states, paving the way for a new Iranian government and a restructured security architecture in the Middle East. In any case, maintaining internal legitimacy in Tehran would be essential, whether through the suppression of hardline elements and easing of repression, or via a flexible balance between marginalizing extremists, implementing institutional reforms, and pursuing “calibrated liberalization”.

Crucially, this transformation must be presented not as an externally imposed solution, but as a “victory of dignity and freedom.”

Central to this scenario, of course, is the suspension of Iran’s military-oriented nuclear program. A new government would need to fully restructure the program, making a public commitment to the peaceful use of nuclear technology under international supervision. Such a move would directly address the red lines of both the United States and Israel, enhance the credibility of the new regime on the international stage, and unlock economic support through the lifting of sanctions and the signing of new trade and energy agreements.

Constructing a Western-Oriented Order

Such a gradual transition of Iran into the Western sphere of influence would bring about profound shifts in the regional geopolitical balance.

The United States would capitalize on the flux of the situation not only to support a friendly government in Tehran but also to reestablish its strategic influence in a region where competition with Eurasian powers has intensified—while those same powers demonstrate limited willingness to respond decisively.

Russia, entangled in prolonged commitments in the war in Ukraine, was unlikely to react meaningfully, opening a second front for the U.S. and the West. China, although invested in Iran through the Belt and Road Initiative, has avoided direct involvement, limiting itself to diplomatic rhetoric. It lacks both the military projection capabilities and the “strategic habit” of external intervention. Moreover, a confrontation with Israel would not serve China’s or Russia’s long-term objectives. The absence of a credible strategic counterweight thus allows the U.S. to shape a new framework of cooperation with key regional actors, with Israel and the Gulf states (Saudi Arabia, the UAE, and Qatar) forming the foundation of this emerging order.

Within this framework, the emergence of a moderate, pro-Western Iran would represent a strategic opportunity to deepen cooperation in energy, trade, security, and infrastructure. Shiite–Sunni tensions would subside, and Tehran’s potential integration into an evolving regional bloc would neutralize the risk of a resurgence of the so-called “Axis of Resistance” (Iran, Syria, Lebanon, Gaza), significantly diminishing the operational capacity of proxy organizations and contributing to greater stability for Israel and the world.

This realignment would also curtail the ideological and operational reach of transnational Islamist organizations such as the Muslim Brotherhood. Additionally, Iran could serve as a strategic lever against Turkey, which maintains opportunistic ties with both China and Russia and has proven unreliable. A reoriented Iran could help restrain Ankara’s revisionist ambitions within a U.S.-led regional order. The cautious consent of Gulf states—traditionally suspicious of Iran’s Shiite influence—would enable a soft endorsement of this moderate transition.

Another ambitious dimension of this optimal scenario would involve the creation of a new energy and trade corridor—or a sub-branch of the India–Middle East–Europe Corridor (IMEC)—connecting the Eastern Mediterranean (Greece, Cyprus, Israel) with a restructured Iran.

This would fall under a broader U.S. strategy to expand and modernize energy and other infrastructure, reduce Europe’s dependence on Russia and Turkey, and support a smooth global energy transition. The proposed “Abraham Accords 2.0” initiative would aim to institutionalize mechanisms for normalization and regional cooperation—preventing the resurgence of future conflicts—by incorporating Iran into a broader framework of regional stability extending into Southeastern Europe.

Breaking the Beijing–Moscow–Tehran Link

A potential regime change in Iran would represent a critical blow to the strategic cohesion of the Eurasian axis. Russia would lose a valuable ally and defense-industrial partner, while China would face significant obstacles to its economic access to the Mediterranean—undermining its efforts to consolidate influence in a strategically vital geography. At the same time, the United States would reaffirm its role as a global balancer and guarantor of international security. Europe, too, would benefit indirectly from the containment of Islamist migration flows toward its territory, while a potential peace in the region would bolster its internal stability and security—especially amid widespread political polarization over recent events. Through energy diversification and improved access to the emerging Eastern Mediterranean–Iran corridor, Europe would also reduce its strategic dependence on both Russia and Turkey.

At the political level, the weakening of the Iranian threat would allow Israel to move toward a logic of regional partnership, shelving its war-centric security posture. The West could further leverage this development as a tool of psychological and cognitive influence against its ideological adversaries. A future dominated by peace and cooperation—under the leadership of American democracy—would signal a symbolic and strategic victory over the autocratic Eurasian powers and their regimes, which might subsequently face internal erosion.

This influence could also extend within Western societies, where liberal-democratic forces might gain ascendancy over ethnonationalist or far-left movements, achieving ideological dominance at home. Notably, the escalating crisis in Los Angeles—bordering on conditions of internal unrest—poses a growing concern for the Trump administration and exemplifies the fragility of domestic political cohesion.

From War to Peace?

The Israel–Iran conflict of June 2025 could mark the beginning of a historic reconfiguration of the Middle East. As outlined, the optimal scenario would go far beyond the collapse of a single regime; it would entail a fundamental redefinition of regional power balances and the restructuring of trade and energy systems—extending Western influence deep into the Eurasian continent while restoring the United States as the legitimate guarantor of global order and security.

However, this vision of peace would only emerge from the crucible of a prolonged war that began in 2023—when Israel severed the regime’s proxy networks before directing its full force against Tehran itself. Rivers of blood, large-scale military operations, and sustained bombardments have shaped the region, reigniting yet another traditional front in the expanding global instability of the early 21st century.

While the temporary ceasefire may offer some potential opportunities, regime change is never a simple undertaking. If the United States seeks to realize this scenario—one that serves its long-term strategic interests—it is likely that the storm must come before the calm. Yet should this trajectory unfold as projected, the map of the Middle East will be redrawn, ushering in a new strategic architecture for the 21st century.
