What Happened
- Ship attacks and maritime disruptions stemming from the 2026 Iran war — including Iranian strikes on Gulf infrastructure, Houthi threats to resume Red Sea attacks, and Iran's Strait of Hormuz closure — have shaken Asian nations' confidence in the US security umbrella.
- Asian economies — particularly China, India, Japan, and South Korea — which collectively account for 75% of oil and 59% of LNG exports transiting through the Gulf, face direct economic exposure that the US has been unable to shield them from.
- The Houthi movement, following a pause in Red Sea attacks from November 2025, threatened to resume maritime attacks in response to the February 28, 2026 US-Israel strikes on Iran, further compounding regional insecurity.
- The episode is prompting a broader reassessment among Asian policymakers of whether the US can reliably project power and protect global commons at the same time it is actively fighting a war in the same region.

US Extended Deterrence and the Security Umbrella in Asia
Extended deterrence is the formal or informal commitment of a major power — especially the United States — to defend allies against threats, including through the use of nuclear weapons as a last resort. The US security umbrella in Asia encompasses treaty allies (Japan, South Korea, Australia, Thailand, Philippines) and de facto security partners (Saudi Arabia, UAE, Israel, Taiwan). The underlying logic is that allies free-ride on US military capacity, spending less on their own defence in exchange for aligning with US strategic interests. However, extended deterrence is only credible when the guarantor power demonstrates both capability and will — and any episode in which the US cannot prevent harm to its allies' economic interests weakens the credibility of the umbrella.
- US Indo-Pacific alliances: ANZUS (Australia, NZ, US), US-Japan Security Treaty (1960), US-ROK Mutual Defence Treaty (1953), US-Philippines Mutual Defence Treaty (1951)
- US maintains roughly 375,000 military personnel deployed in the Indo-Pacific
- India is not a formal US ally but has signed the four Foundational Defence Agreements (BECA, LEMOA, COMCASA, GSOMIA) and participates in Quad security dialogue
Connection to this news: If the US, actively engaged in combat operations against Iran, cannot reopen the Strait of Hormuz or protect Gulf Arab infrastructure, Asian allies and partners will increasingly question whether US security guarantees are bankable in a crisis.
Houthi Attacks and Red Sea Maritime Security
The Houthi movement (Ansar Allah), based in Yemen, controls much of northern Yemen including the Bab-el-Mandeb strait — the other critical chokepoint linking the Red Sea to the Gulf of Aden. Beginning in late 2023, the Houthis launched a sustained campaign of missile and drone attacks against commercial vessels in the Red Sea, ostensibly in solidarity with Gaza. This forced major shipping lines to reroute around the Cape of Good Hope, adding weeks to voyage times and significantly raising freight costs. The US-led Operation Prosperity Guardian (launched December 2023) deployed a multinational naval coalition to protect Red Sea shipping but could not fully suppress the attacks. The resumption of Houthi threats in 2026 compounds the Strait of Hormuz crisis, potentially threatening both of the western Indian Ocean's key chokepoints simultaneously.
- Bab-el-Mandeb: ~30 km wide; approximately 10% of global trade and ~9 mb/d of oil transits annually
- Houthi attacks (2023–2025): forced 60%+ of container shipping to reroute to Cape of Good Hope
- Cape of Good Hope rerouting adds ~14 days to Europe-Asia voyages and raises shipping costs by 30–50%
- UN Security Council Resolution 2722 (2024) condemned Houthi attacks; UNSC Resolution 2812 (2026) extended reporting mandate
Connection to this news: Simultaneous threats to both the Strait of Hormuz and the Red Sea/Bab-el-Mandeb represent an unprecedented dual chokepoint crisis, with no adequate US-led solution in sight.
Indo-Pacific Security Architecture and India's Strategic Positioning
India has adopted a policy of "strategic autonomy," avoiding formal military alliances while building partnerships with multiple major powers. India participates in the Quad (India, US, Australia, Japan) — a security dialogue that has evolved toward a broader Indo-Pacific cooperation framework — while maintaining strategic and defence ties with Russia and engaging with Gulf states diplomatically. The erosion of confidence in the US security umbrella, paradoxically, may create space for India to enhance its own strategic footprint in the Indian Ocean Region (IOR), consistent with its stated vision of being a "net security provider" in the region.
- India's "Neighbourhood First" and "SAGAR" (Security and Growth for All in the Region) doctrines articulate its Indian Ocean ambitions
- India's naval deployments in the Arabian Sea have increased since the Houthi crisis began
- The Quad's joint naval exercises (MALABAR exercises) are partly aimed at ensuring freedom of navigation in the Indo-Pacific
Connection to this news: As US credibility as a maritime security guarantor comes under stress, India faces both a challenge (energy supply disruption) and an opportunity (greater regional security leadership) in the evolving Indo-Pacific order.
