What Happened
- Ahead of talks between US and Iranian representatives in Islamabad — facilitated by Pakistan — US President Donald Trump publicly asserted that Iran holds only one meaningful card: its ability to threaten or block oil transit through the Strait of Hormuz.
- Trump posted on his Truth Social network that "the Iranians don't seem to realise they have no cards, other than a short term extortion of the World by using International Waterways," framing Iran's Hormuz leverage as temporary and characterising Iran as acting under duress.
- The statement signals the strategic framework Washington is bringing to nuclear-and-sanctions negotiations: Iran's energy-chokepoint leverage is real but finite, and the US calculates Iran has more to lose by prolonged confrontation.

Strait of Hormuz — Geography and Strategic Significance
The Strait of Hormuz is a narrow waterway between the Musandam Peninsula (Oman) to the south and the Iranian coast to the north, connecting the Persian Gulf (Arabian Gulf) to the Gulf of Oman and onward to the Arabian Sea. It is the world's most critical maritime oil chokepoint.
- Narrowest width: approximately 34 kilometres (21 miles) at its narrowest point
- Shipping lanes: two unidirectional lanes, each 3 km (2 miles) wide, separated by a 3 km buffer zone — all located primarily within Omani territorial waters and partially within Iranian territorial waters
- Oil volume: flows through the Strait in 2024–25 represent more than one-quarter of total global seaborne oil trade and roughly one-fifth of global oil and petroleum product consumption — approximately 20 million barrels of oil per day
- Major exporters transiting Hormuz: Saudi Arabia, the UAE, Iraq, Kuwait, Qatar, and (partially) Iran itself
- The Strait is also critical for LPG and LNG shipments from Qatar, the world's largest LNG exporter
- There is no alternative route of comparable capacity: the Saudi Arabian East-West Pipeline (to Yanbu on the Red Sea) provides partial bypass but at significantly lower volumes
Connection to this news: Trump's statement is a precise geopolitical observation: Iran's single most consequential coercive instrument is the threat to close or disrupt the Strait of Hormuz. Iran has repeatedly signalled this capacity during periods of tension, most recently amid US sanctions and the risk of Israeli-US military action. The framing of Hormuz as "short-term extortion" reflects Washington's calculation that an actual closure would devastate Iran's own oil export revenues — making the threat economically self-defeating for Tehran.
UNCLOS and the Right of Transit Passage Through International Straits
The United Nations Convention on the Law of the Sea (UNCLOS), concluded in 1982 and in force from 1994, established a specific legal regime for navigation through straits used for international navigation — replacing the narrower "innocent passage" concept.
- Transit passage (Part III, Articles 37–44 of UNCLOS): All ships and aircraft — including warships, submarines (submerged), and military aircraft — have the right to transit through straits used for international navigation "in a continuous and expeditious manner" without prior notification or permission from the coastal state
- Unlike innocent passage (applicable in territorial seas), transit passage cannot be suspended by the coastal state, even temporarily
- The coastal state (here, Iran and Oman) can adopt laws and regulations on transit passage only in narrowly defined areas: safety of navigation, prevention of pollution, and fishing — not security restrictions that would effectively block transit
- Iran is not party to UNCLOS — it has signed but not ratified the Convention — and maintains that foreign warships require prior authorisation to transit its territorial waters. This position is rejected by the US and most major naval powers
- The 2026 Strait of Hormuz crisis (following rising US-Iran tensions) has renewed attention to the gap between Iran's legal position and the transit passage regime observed by the international community
Connection to this news: Trump's characterisation of Iran's Hormuz leverage as "extortion of international waterways" is legally grounded in the transit passage doctrine — from the US perspective, Iran has no right under international law to restrict transit, so any attempt to do so would be an unlawful act. Iran's counter-position (that it controls its territorial waters) sets up the legal and military confrontation that makes Hormuz diplomacy so high-stakes.
India's Energy Security and the Hormuz Dependency
India is the world's third-largest oil consumer and imports approximately 85–88% of its crude oil requirements. The Strait of Hormuz is the exit corridor for the Persian Gulf producers that supply roughly half of India's crude oil.
- Approximately 50% of India's crude oil imports and most of its LPG transits through the Strait of Hormuz
- India's primary Gulf suppliers include Iraq (India's largest crude supplier), Saudi Arabia, UAE, and Kuwait — all whose exports exit via Hormuz
- India resumed crude oil imports from Iran in 2025 after a seven-year gap following US sanctions waiver issues; Iranian crude adds to Hormuz-dependent supply
- India has no alternative pipeline route for Gulf oil; any Hormuz disruption would immediately impact domestic fuel prices and energy supply security
- India abstains from UN votes directly condemning Iran to preserve energy and diplomatic flexibility — making the US-Iran standoff a delicate foreign policy management challenge for New Delhi
Connection to this news: Any Hormuz disruption — even a temporary Iranian threat or actual mining — would send global oil prices sharply higher and directly strain India's import bill and current account deficit. The US-Iran talks in Islamabad are therefore not merely a bilateral matter: their outcome directly affects India's energy security calculus and its strategic balancing between Washington and Tehran.
West Asia in India's Foreign Policy
India follows a multi-alignment strategy in West Asia — maintaining close ties simultaneously with Iran (energy, Chabahar port connectivity to Central Asia and Afghanistan), the Gulf states (diaspora remittances, energy supply), Israel (defence, technology), and the US (strategic partnership). India does not take sides in intra-regional rivalries or US-Iran confrontations.
- India's Chabahar Port (Iran, on the Gulf of Oman) provides a non-Hormuz trade corridor to Afghanistan and Central Asia — reducing India's vulnerability to Hormuz blockage for non-oil trade
- The Iran-Pakistan-India (IPI) gas pipeline project remains dormant due to sanctions and India-Pakistan relations — making pipeline diversification unavailable
- India's "Connect Central Asia" and International North-South Transport Corridor (INSTC) both route through Iran, giving India a strategic interest in Iran's stability and accessibility
- India's US $6 billion+ annual remittances from the Gulf Arab states — and the welfare of nearly 9 million Indian diaspora in the region — create an additional stake in regional stability
Connection to this news: Pakistan hosting US-Iran talks in Islamabad is itself a significant development: it positions Pakistan as a regional mediator, potentially complicating India's regional calculus. India's response will be to watch closely while maintaining equidistance — a stance consistent with its traditional approach to West Asian conflicts.
