United States–Iran Ceasefire — Hormuz, Nuclear Talks, and India’s Stakes

General Studies Paper 2 — International Relations
Source: United States Central Command / May 2026

1. What happened

The United States and Iran have drawn up a tentative 60-day ceasefire Memorandum of Understanding following direct military exchanges. The truce is yet to receive final approval from US President Donald Trump.

Pakistan is playing an active diplomatic mediator role — its Foreign Minister Ishaq Dar travelled to Washington to stabilise the truce.

2. How the conflict escalated — the key events

Escalation timeline — United States vs Iran, 2026

1. United States strikes Bandar Abbas, Iran

United States Central Command (CENTCOM) hit a ground control station in Bandar Abbas — Iran’s key strategic port on the Strait of Hormuz — destroying five attack drones.

Bandar Abbas = Iran’s main port on the Strait of Hormuz

2. Iran retaliates — strikes United States airbase in Kuwait

Iran’s Islamic Revolutionary Guard Corps (IRGC) fired ballistic missiles at a United States airbase in Kuwait. Kuwait’s military intercepted the missile.

IRGC = Iran’s elite paramilitary force, separate from the regular army

3. Hormuz toll dispute — United States warns Oman

Iran and Oman proposed imposing maritime tolls on ships using the Strait of Hormuz. The United States warned this violates international law and threatened military action to protect freedom of navigation.

Violation of UNCLOS Transit Passage rights

4. 60-day ceasefire proposed

A Memorandum of Understanding drafted — key terms: 60 days to negotiate Iran’s uranium stockpile, no United States sanctions relief, maritime corridors to reopen.

3. Why India is directly affected

1. Energy Security

India imports over 80% of its crude oil — a large portion through the Strait of Hormuz. Any blockade spikes the import bill, widens the Current Account Deficit, and raises domestic fuel prices.

2. Chabahar Port and INSTC

India’s investment in Iran’s Chabahar Port and the International North-South Transport Corridor (INSTC) — India’s strategic trade route to Central Asia — requires stability in the Gulf of Oman.

3. Indian Diaspora

Millions of Indian expatriates live across Gulf countries including Kuwait. A full-scale war would require a large-scale evacuation — like Operation Kaveri (Sudan, 2023) but far larger.

4. Value Box — Key Terms

Transit Passage — UNCLOS

Under the United Nations Convention on the Law of the Sea, all ships and aircraft have the uninterrupted right of passage through international straits (like Hormuz) used for navigation. No country can impose tolls or block this passage — doing so violates international law.

Islamic Revolutionary Guard Corps (IRGC)

Iran’s elite paramilitary force — separate from the regular Iranian army. Controls Iran’s missile programme, naval operations in the Gulf, and proxy networks across West Asia. Designated as a terrorist organisation by the United States.

Chabahar Port and INSTC

India-developed deep-water port in Iran on the Gulf of Oman. Gateway to the International North-South Transport Corridor — a 7,200 km multi-modal route connecting India to Russia and Central Asia via Iran, bypassing Pakistan.

Prelims Practice Question

Consider the following statements regarding the United States–Iran conflict and the Strait of Hormuz:

1. Under the United Nations Convention on the Law of the Sea, the Strait of Hormuz is governed by “Transit Passage” rights — meaning no country can impose tolls or block ships from passing through it.
2. The Islamic Revolutionary Guard Corps is Iran’s regular national army and is under the direct command of the Iranian President.
3. India’s Chabahar Port investment in Iran is strategically linked to the International North-South Transport Corridor, which connects India to Russia and Central Asia bypassing Pakistan.

• (a) 1 and 2 only
• (b) 1 and 3 only
• (c) 2 and 3 only
• (d) 1, 2 and 3

Correct Answer: (b) 1 and 3 only
