US President Donald Trump warns of intensified military action against Iran

The recent escalation in the Persian Gulf, marked by US President Donald Trump's warning of intensified military action against Iran, represents a critical flashpoint in international relations with profound implications for global energy security and regional stability. To understand the current crisis, we must trace its roots to the 2015 Joint Comprehensive Plan of Action (JCPOA), commonly known as the Iran nuclear deal, signed between Iran and the P5+1 nations (US, UK, France, Russia, China, plus Germany). The agreement, endorsed by UN Security Council Resolution 2231, provided sanctions relief to Iran in exchange for verifiable limits on its nuclear programme. However, in May 2018, the Trump administration unilaterally withdrew from the JCPOA, reimposing stringent economic sanctions under the 'maximum pressure' campaign, targeting Iran's oil exports, banking sector, and key industries. This move fundamentally altered the regional security architecture, prompting Iran to gradually breach its nuclear commitments and adopt asymmetric tactics, including attacks on commercial shipping in the Strait of Hormuz — through which approximately 20-30% of the world's seaborne crude oil passes daily. The key stakeholders in this crisis extend beyond the US and Iran. Kuwait's interception of hostile drones targeting vital infrastructure underscores the vulnerability of Gulf Cooperation Council (GCC) states, particularly Saudi Arabia and the UAE, which host major US military bases and rely on the Strait for energy exports. Iran's Islamic Revolutionary Guard Corps (IRGC), designated a foreign terrorist organization by the US in 2019, employs proxy forces such as the Houthis in Yemen and militias in Iraq to project power and threaten shipping lanes. Meanwhile, major oil importers — China, India, Japan, South Korea, and the European Union — face acute energy security risks. For India, which imports over 80% of its crude oil, any disruption in the Strait of Hormuz directly impacts inflation, current account deficit, and fiscal stability. In 2018-19, India sourced about 10-12% of its crude from Iran before US sanctions forced a complete halt under the 'significant reduction exception' waiver expiry in May 2019. Constitutionally, India's response falls under Article 246 and Entry 14 of the Union List (Seventh Schedule), which empowers Parliament to legislate on 'entering into treaties and agreements with foreign countries and implementing of treaties, agreements and conventions with foreign countries.' The Ministry of External Affairs, guided by the National Security Council (established 1998), formulates policy under the executive power of the Union (Article 53 and 73). India's strategic autonomy doctrine, articulated in the 2015 'Joint Strategic Vision for the Asia-Pacific and Indian Ocean Region' with the US, and its 'Look West' policy, necessitate a balanced approach — maintaining defence ties with the US (including COMCASA, LEMOA, BECA agreements) while preserving energy and connectivity interests with Iran (Chabahar Port development under a 2016 trilateral agreement with Afghanistan). The broader themes at play include freedom of navigation under UNCLOS (United Nations Convention on the Law of the Sea, 1982), to which India is a party, and the role of the International Maritime Organization (IMO) in securing global shipping lanes. The crisis also tests the relevance of multilateral forums like the UN Security Council, where permanent members remain divided, and the International Court of Justice, where Iran filed a case against US sanctions in 2018 citing the 1955 Treaty of Amity. Future implications are deeply concerning. A military confrontation could trigger a global oil price shock, potentially pushing Brent crude above $100/barrel, derailing post-pandemic economic recovery. For India, this would widen the current account deficit, weaken the rupee, and constrain RBI's monetary policy space. Strategically, India may face pressure to join US-led maritime security initiatives like the International Maritime Security Construct (IMSC), risking Iranian retaliation against Chabahar investments. Diplomatically, India must leverage its unique position — as a major economy with ties to all parties — to advocate de-escalation, possibly through the 'Tehran Dialogue' or backchannel diplomacy. Aspirants should monitor developments in the IAEA Board of Governors meetings, US-Iran indirect talks in Oman, and the evolving India-US 2+2 Ministerial Dialogue outcomes for cues on India's strategic calculus.
