Iran, US on brink of war again: For India, a lot to watch out for

📌 Summary:

• Context: The US and Iran have attacked each other in the past week, shredding the Memorandum of Understanding (MoU) they signed on June 17; two US military personnel were killed in Jordan on Saturday and the US retaliated, raising the spectre of all-out war

• The core stake — Strait of Hormuz: The MoU had hinged on Iran's demonstrated capability to control the strait, through which 20% of the world's energy supply flows; current tensions turn on the US trying to prove it can loosen Tehran's chokehold on the waterway

• Human toll: Iran says US strikes have killed at least 50 people and wounded more than 500 in the post-MoU round

• Why Iran will not back down: two reasons — the conviction that the US cannot be trusted, and the imperative of retaining control over Hormuz as its single biggest source of leverage

• Iran's new Ayatollah, Mojtaba Khamenei, posted on X on July 18 that "repeated breaches of the agreement" show the US President's signature is "utterly worthless and devoid of credibility"

• Legal-economic manoeuvre: Per the Institute for the Study of War (ISW), an Iranian Environmental Protection Agency official said on July 18 that the body had asked the government to charge ships transiting the strait fees for "environmental services", invoking the UN Convention on the Law of the Sea (UNCLOS) — an attempt to formalise transit charges and control

• Military adaptation: Iran has fired high-speed, manoeuvrable missiles at US bases in neighbouring countries; ISW says Iranian leaders focused on missile accuracy after the 12-day war of June 2025, and after poor accuracy against Israeli targets in March-April 2026 likely deployed cluster munitions at greater scale to maximise damage

• US lesson: A re-learning of the post-Afghanistan and post-Iraq lesson that too much firepower, poorly applied, only produces more enemies; the US goal now is to keep Hormuz free for movement as it was before the US and Israel attacked Iran on February 28

• India's stakes — human: Many Indians live and work in West Asia and a large share of global ship crews are Indian; 14 Indians have died since the war began on February 28 and two are missing. Delhi has protested to both Iran and the US over these deaths, mostly of seafarers and Gulf-based workers

• India's stakes — economic: Rising energy prices are creating headwinds for the Indian economy and hitting markets; the inflationary impact of West Asian developments is already visible

• India's position: New Delhi is urging both parties to return to dialogue and diplomacy, and not to push the global economy into a slowdown in which the Global South suffers

🎯 UPSC Relevance: GS2 — India and West Asia, energy security as a driver of foreign policy, and India's balancing between the US and Iran. GS3 — impact of external shocks on inflation and growth. Also relevant to maritime chokepoints and UNCLOS.

📝 Prelims Facts:

• The Strait of Hormuz connects the Persian Gulf to the Gulf of Oman and the Arabian Sea, lying between Iran and Oman (Musandam exclave); about 20% of world energy supply transits it
• UNCLOS governs transit passage through international straits
• ISW (Institute for the Study of War) is an American think tank
• Mojtaba Khamenei is Iran's new Ayatollah

🔑 Key Term: Chokepoint — a narrow, strategically critical maritime passage whose closure or disruption can constrict a disproportionate share of global trade or energy flows; Hormuz, Malacca, Bab-el-Mandeb and Suez are the principal examples.
