U.S. launches more strikes on Iran as standoff over Strait of Hormuz escalates

The recent U.S. strikes on Iranian military assets in the Strait of Hormuz represent a significant escalation in the long-standing geopolitical rivalry between Washington and Tehran, with profound implications for global energy security and regional stability. To understand this development, we must trace the historical context: tensions have simmered since the 1979 Iranian Revolution, which ousted the U.S.-backed Shah and established the Islamic Republic, leading to the severance of diplomatic relations. The 2015 Joint Comprehensive Plan of Action (JCPOA) temporarily eased tensions by curbing Iran's nuclear programme in exchange for sanctions relief, but the U.S. withdrawal under the Trump administration in 2018 and the reimposition of 'maximum pressure' sanctions reignited hostilities. Since then, Iran has progressively breached nuclear limits, while proxy conflicts have flared across West Asia — in Yemen, Syria, Iraq, and Lebanon — often threatening maritime routes. The Strait of Hormuz, a narrow 39-kilometre-wide chokepoint between the Persian Gulf and the Gulf of Oman, is the world's most critical oil transit artery. Approximately 20-30% of global oil consumption — about 21 million barrels per day — passes through it, including over 80% of China's and 70% of India's crude oil imports. Any disruption here sends shockwaves through global energy markets, spiking prices and triggering inflationary pressures worldwide. The Islamic Revolutionary Guard Corps (IRGC) Navy, a paramilitary force separate from Iran's regular navy, has repeatedly harassed commercial vessels, seized tankers, and deployed mines and drones in these waters, asserting Tehran's ability to close the strait if provoked. The U.S. strikes, targeting IRGC missile systems, air defence installations, and fast-attack boats at multiple locations, signal a strategic shift from passive deterrence — such as naval escorts and coalition patrols under Operation Sentinel — to active degradation of Iran's offensive capabilities. This reflects a broader U.S. policy recalibration under the Biden administration, balancing diplomatic overtures with credible military deterrence. Key stakeholders include not just the U.S. and Iran, but also Gulf Cooperation Council (GCC) states like Saudi Arabia and the UAE, which rely on the strait for exports; major energy importers like India, China, Japan, and South Korea; and global powers like Russia and China, which have deepening strategic ties with Tehran. For India, the stakes are exceptionally high. As the world's third-largest oil consumer and importer of over 85% of its crude needs, India is acutely vulnerable to Hormuz disruptions. In 2022-23, Iraq, Saudi Arabia, and the UAE were India's top three crude suppliers, with significant volumes transiting the strait. A sustained closure could trigger a balance-of-payments crisis, widen the current account deficit, fuel domestic inflation, and strain fiscal space for social spending. Politically, India maintains a delicate balancing act: it has deep civilisational and energy ties with Iran (including the Chabahar Port project, vital for access to Afghanistan and Central Asia), while simultaneously strengthening strategic partnerships with the U.S. (Quad, defence deals, technology cooperation) and Gulf states (diaspora, remittances, investment). Article 51 of the Indian Constitution mandates the State to promote international peace and security, and India has consistently advocated dialogue and diplomacy — evident in its abstention on UN resolutions condemning Iran and its call for de-escalation. The Maritime Security Strategy (2015) and the SAGAR (Security and Growth for All in the Region) doctrine underscore India's commitment to securing sea lanes of communication. Broader themes at play include the erosion of the post-WWII liberal maritime order, the weaponisation of energy interdependence, and the growing role of non-state and paramilitary actors in hybrid warfare. The strikes also raise questions about the legality of pre-emptive self-defence under Article 51 of the UN Charter, especially absent a UN Security Council mandate. Future implications are uncertain: Iran may retaliate asymmetrically via proxies (Hezbollah, Houthis, Iraqi militias) or cyberattacks; oil markets may price in a 'risk premium'; and diplomatic efforts to revive the JCPOA could stall further. For aspirants, this episode is a living case study in strategic geography, energy security, international law, and India's multi-alignment foreign policy — all core to UPSC GS Paper II (International Relations), GS Paper III (Security, Economy), and Essay. Understanding the interplay of hard power, economic leverage, and diplomatic nuance here is essential for analysing contemporary global disorder.
