Analyse the impact of the 2026 Iran–Israel–US conflict on the security architecture of the Gulf region and its implications for India.

The 2026 Israel–US strikes on Iran and Iran's retaliation against US military installations hosted in the Gulf converted West Asia's deterrence-based order into open inter-state conflict, drawing Arab monarchies into a war they had sought to avoid — with direct consequences for India's energy, diaspora and connectivity interests.

Decomposing the impact on Gulf security architecture

• Erosion of the US security umbrella: American bases, long the guarantor of Gulf security, became Iran's declared targets, exposing host states such as the UAE to costs they had not bargained for.
• Collapse of Iran–Gulf normalisation: Iranian strikes and UAE retaliation, followed by suspension of trade and financial exchanges, reversed the post-2023 détente between Tehran and the Arab monarchies.
• Militarisation of chokepoints: threats around the Strait of Hormuz turned shipping lanes and energy infrastructure into instruments of coercion, endangering civilian infrastructure and global supply chains [1].
• Search for new managers of the peace: with Western mediation distrusted, non-Western platforms gained salience — India's 18th BRICS Summit hosted both the Iranian President and the Abu Dhabi Crown Prince, enabling their first direct engagement since the war began [5].

Implications for India

• Energy security: diversified sourcing from about 40 countries raised crude arriving outside the Strait of Hormuz from roughly 55% to 70%, though nearly 90% of imported LPG still transits Hormuz [3], prompting parliamentary assurances on supply management [4].
• Diaspora and remittances: about one crore Indians in the GCC required contingency monitoring for safety and evacuation [3].
• Diplomatic balancing: India must sustain Chabahar-linked ties with Iran alongside deep Gulf partnerships, while its BRICS chairship faced visible difficulty in forging consensus among members directly involved [2].
• Strategic autonomy: the New Delhi Declaration urged restraint, protection of civilians and dialogue without naming parties [1].

Reassembled, the conflict has replaced external guarantees with contested, self-help security in the Gulf. India's calibrated response — supply diversification, diaspora protection and issue-based convening — positions it as a credible bridge-builder, and deepening this de-escalation diplomacy best secures both regional stability and India's own strategic autonomy.
