What Happened
- US President Trump announced that multiple countries would send warships to the Persian Gulf to help keep the Strait of Hormuz open for commercial shipping amid Iran's blockade.
- Trump named China, France, Japan, South Korea, and the United Kingdom as among those he hoped would contribute to what he described as an emerging naval coalition.
- The response from potential coalition partners was lukewarm: South Korea said it would "closely coordinate and carefully review" the situation; France said any mission would need to wait until "the circumstances permit" (i.e., after fighting subsides); China gave no immediate response.
- The announcement came after commercial shipping through the Strait had been brought to an almost complete halt, with oil prices above $100/barrel and global supply chains severely disrupted.
- The US already maintained a significant naval presence in the region through the 5th Fleet (Bahrain) and carrier strike groups, but Trump sought to internationalise the burden of keeping the waterway open.
What Happened (continued — context)
- Iran's position was that the Strait was closed only to US and Israeli ships, with other countries' vessels potentially allowed passage subject to Iranian decision-making — a policy Iran used to selectively allow Indian and other countries' vessels through.
- Two Indian-flagged vessels (Shivalik and Nanda Devi) were permitted through the Strait on March 14, illustrating Iran's selective approach to the blockade.

Freedom of Navigation Operations (FONOPs) and Naval Coalitions
Freedom of Navigation Operations are US Navy missions designed to assert navigational rights and freedoms under international law by sailing or flying through areas claimed by another state. In the context of the Hormuz crisis, the proposed naval coalition goes beyond FONOP — it would involve escort operations for commercial vessels, similar to past Gulf convoy missions.
- Operation Earnest Will (1987–88): The largest peacetime naval convoy operation, where the US escorted Kuwaiti tankers reflagged as US vessels through the Persian Gulf during the Iran-Iraq Tanker War
- Operation Prosperity Guardian (2023–24): US-led naval coalition formed to protect commercial shipping from Houthi attacks in the Red Sea; included UK, Bahrain, Canada, and others
- Combined Maritime Forces (CMF) is a US-led naval partnership based in Bahrain with 38 member nations that conducts maritime security operations in the Middle East
- NATO Article 5 collective defence obligations do not extend to the Persian Gulf, limiting automatic alliance obligations for European members
Connection to this news: Trump's proposed naval coalition follows a well-established template — the 1987 Gulf escort mission and the 2023 Red Sea coalition — but faces the challenge that active US-Iran combat makes neutral naval participation far more politically risky for third countries.
The Strait of Hormuz — Legal Status and Passage Rights
The Strait of Hormuz is an international strait under customary international law, with transit passage rights enshrined in UNCLOS Article 38. The navigable channel runs through the territorial waters of both Iran (northern shore) and Oman (southern shore). Iran has long claimed it can regulate or close the strait, while international law holds that transit passage cannot be suspended.
- UNCLOS Article 38: Ships of all states enjoy transit passage through international straits
- UNCLOS Article 44: Coastal states "shall not hamper transit passage" — non-suspendable
- Iran is not a party to UNCLOS (signed but not ratified), but the transit passage regime is widely regarded as binding customary international law
- The US is also not party to UNCLOS, but invokes its provisions to justify freedom of navigation
- Iran's selective allowance of non-US/Israeli vessels reflects a political rather than legal framing of the blockade
Connection to this news: The proposed naval coalition seeks to enforce the customary international law principle of free transit passage — with military presence substituting for legal compliance where Iran refuses to be bound by treaty.
Burden-Sharing in US-Led Security Arrangements
A recurring theme in US foreign policy is the tension between America's role as a global security guarantor and its expectation that allies share the burden of maintaining international order. This manifests in repeated US calls for NATO allies to increase defence spending (2% of GDP target) and for Asian partners to contribute more to regional security.
- Japan's defence policy underwent a historic shift in December 2022 with its revised National Security Strategy, doubling defence spending to 2% of GDP and acquiring counterstrike capabilities
- South Korea operates a significant naval force in the Indo-Pacific but is constitutionally and politically cautious about overseas military deployments
- France maintains an active Indo-Pacific defence posture, with naval forces and bases in Djibouti and Réunion
- China's participation in a US-led Gulf coalition would be historically unprecedented and politically improbable given US-China competition
- The 2023 Red Sea coalition (Operation Prosperity Guardian) showed that European allies would join US-led maritime security operations — but an active war with Iran raises the bar significantly
Connection to this news: The reluctance of Japan, South Korea, France, and China to immediately commit warships reflects the fundamental difference between peacetime FONOP support and joining an active combat zone — illustrating the limits of US alliance burden-sharing in high-intensity conflicts.
India's Stance — Strategic Neutrality and Bilateral Engagement
India, despite being severely affected by the Hormuz blockade, has not been invited to join or publicly committed to joining any naval coalition. India's approach has been to pursue bilateral diplomacy with Iran to secure passage for its vessels rather than aligning with a US-led military posture.
- India maintains the Indian Navy's Western Naval Command as responsible for the Persian Gulf/Arabian Sea region
- India's Constitution and strategic culture strongly favour non-intervention and bilateral diplomacy over military coalitions in third-country conflicts
- India's successful diplomacy in securing passage for the Shivalik and Nanda Devi was achieved through bilateral channels, not coalition pressure
- India-Iran relations include the Chabahar Port agreement and historical energy trade — these diplomatic assets give India leverage for bilateral solutions
- India's non-alignment tradition, while evolved into "strategic autonomy," continues to make formal military coalition participation in West Asia unlikely
Connection to this news: India's absence from the proposed coalition — despite being one of the countries most affected by the Hormuz blockade — illustrates how strategic autonomy leads India to pursue parallel diplomatic tracks rather than joining US-led military postures.
