US-Israel War on Iran: What Price for a Lasting Peace |
The military campaign conducted by Israel and the United States against Iran—inaugurated in June 2025 and intensified in February 2026—constitutes one of the most consequential armed confrontations in the contemporary Middle East. Targeting Iran’s nuclear infrastructure, military command, and political leadership, the strikes inflicted severe but ultimately incomplete damage on Tehran’s atomic program while generating a complex web of diplomatic, legal, and strategic dilemmas.
This essay argues that durable peace between the parties requires a comprehensive framework addressing five interlocking dimensions: verifiable nuclear disarmament and IAEA transparency, the resolution of the Strait of Hormuz dispute, regional security architecture that integrates Iran’s legitimate interests, economic normalization through phased sanctions relief, and multilateral guarantees of Iranian sovereignty. Drawing on primary sources, parliamentary briefings, and expert analyses from the Arms Control Association, Carnegie Endowment for International Peace, and the UN Security Council, the essay demonstrates that military coercion alone cannot substitute for sustained diplomacy. The current ceasefire, brokered by Pakistan in April 2026, is fragile and contingent; transforming it into a lasting peace will demand sacrifices—and political will—from all parties.
The military escalation between Israel, the United States, and Iran that began on June 13, 2025 and re-escalated dramatically on February 28, 2026, represents a watershed in the geopolitics of the greater Middle East. What had long been contemplated as a theoretical preventive strike—Israel destroying Iran’s nuclear capacity before Tehran crossed the threshold to weapons capability—became operational reality, drawing in American forces and igniting a conflict of regional proportions. By the time Pakistan brokered a conditional ceasefire on April 8, 2026, the war had claimed over a thousand Iranian lives (House of Commons Library, 2025a), disrupted global shipping through the Strait of Hormuz, triggered the reinstatement of comprehensive UN sanctions, and left the architecture of nuclear nonproliferation in severe disrepair (Arms Control Association, 2025a).
Yet the central question—what a lasting peace would require and at what political and strategic price—remains unanswered. A ceasefire is not peace. The current halt to hostilities is conditional on unresolved disputes over nuclear enrichment, Hormuz navigation rights, sanctions relief, Iranian sovereignty claims, and the future of Tehran’s regional proxy networks (House of Commons Library, 2026a). This essay examines the origins and conduct of the conflict, analyzes the principal obstacles to a durable settlement, and proposes the conditions under which a comprehensive peace might be achieved. It argues that the price of lasting peace is high—but the price of its absence is higher.
Origins: From Maximum Pressure to Military Action
The conflict did not erupt spontaneously. It was the product of a decade-long accumulation of strategic grievances, failed diplomacy, and escalating nuclear activities. The Joint Comprehensive Plan of Action (JCPOA), concluded in July 2015 by Iran and the P5 1 under President Barack Obama’s administration, imposed verifiable limits on Iran’s uranium enrichment in exchange for sanctions relief (Council on Foreign Relations, 2023). The agreement required Iran to reduce its enriched uranium stockpile by 97%, cap enrichment at 3.67%, and submit to intrusive International Atomic Energy Agency (IAEA) inspections (EBSCO Research Starters, n.d.).
When President Donald Trump unilaterally withdrew from the JCPOA in 2018—despite Iran’s verified compliance—and reimposed maximum pressure sanctions, he shattered the diplomatic framework without offering a viable alternative (Carnegie Endowment for International Peace, 2026). Iran responded by progressively breaching JCPOA limits: by March 2025, its stockpile of uranium enriched to 60% U-235 had reached 275 kg, nearly weapon-relevant concentrations, up from 182 kg just months earlier (Arms Control Center, 2025). By May 2025, a confidential IAEA report confirmed that Iran possessed over 400 kg of uranium enriched to 60% purity—a 50% increase since February (Arms Control Center, 2025).
Upon returning to office in his second term, Trump prioritized a new nuclear deal and launched five rounds of indirect Omani-mediated talks with Tehran beginning April 12, 2025 (Britannica, 2026). U.S. Special Envoy Steve Witkoff and Iranian Foreign Minister Abbas Araghchi led the discussions. Three core issues dominated: verification measures, the disposition of Iran’s enriched uranium stockpile, and the future of Iranian enrichment rights—with Washington demanding zero enrichment and Tehran insisting on its inalienable right under international law to enrich uranium for peaceful purposes (Wikipedia, 2026a). A sixth round scheduled for June 15 was cancelled when Israel launched strikes on June 13 (House of Commons Library, 2025b).
The Twelve-Day War and its Strategic Logic
Israel’s June 2025 campaign—codenamed Operation Narnia—was a carefully premeditated operation combining covert intelligence assets, precision airstrikes on nuclear facilities, and the targeted killing of at least 14 senior Iranian nuclear scientists (House of Commons Library, 2025b; i24News, 2025). Initial Israeli targets included Natanz and Isfahan, as well as senior commanders of the Islamic Revolutionary Guard Corps (IRGC) and senior military leaders (Arms Control Association, 2025b). Israeli Prime Minister Benjamin Netanyahu offered no intelligence suggesting an imminent Iranian nuclear threat; rather, he stated the campaign aimed to ‘eliminate’ Iran’s nuclear and missile programs (Arms Control Association, 2025b).
Crucially, Israel lacked the military capability to penetrate Iran’s most deeply buried facilities—particularly Fordow—and the strategic logic of the operation was, in part, to draw the United States into direct participation (Arms Control Association, 2025b). That logic succeeded. On June 21-22, 2025, U.S. forces struck Fordow, Natanz, and Isfahan with GBU-57 Massive Ordnance Penetrator bombs delivered by B-2 Spirit stealth bombers—the first direct American military attack on Iran’s nuclear program in history (Congressional Research Service, 2025). The IAEA Director General acknowledged that ‘very significant damage is expected to have occurred’ at Fordow but cautioned that Iran retains the industrial capacity and knowledge to resume enrichment, and that ‘ultimately diplomacy and inspections are required to restrict its programme’ (House of Commons Library, 2025a).
Iran retaliated by launching ballistic missiles against the Al-Udeid U.S. Air Base in Qatar on June 23, but provided advance warning, causing no American casualties—a signal that Tehran sought to avoid uncontrolled escalation with Washington (Arms........
