Impact on India

  • Economy
  • Iran has instructed Houthis to close the Red Sea gateway if the US hits Iran’s power infrastructure. The possible closure of the Bab el-Mandeb Strait could pose additional economic challenges for India. A significant majority of India’s maritime shipping to Europe, North America, North Africa, and parts of West Asia passes through the Strait of Hormuz and the Bab-el-Mandeb Strait. Given the reduced traffic through the Strait of Hormuz, a huge part of this trade has been dependent on the Red Sea corridor for 50 percent of its merchandise exports and 30 percent of its imports. Within that, 80 percent of India’s trade with Europe moves through the Red Sea and the Suez Canal, which will be heavily affected if the region is closed.

Key Actors

  • Iran

  • Iran enters its sixth consecutive day of active combat with the US since the ceasefire collapsed, facing strikes on command centres, missile sites, and, for the first time, a US sea-drone attack on its Bandar Abbas naval base. Tehran has responded; however, its retaliatory capacity seems reportedly degraded and improvised rather than strategic. Domestically, the regime is purportedly fraying under a projected -5.4% GDP contraction, capital flight exceeding 7 percent of the economy, and protests by retirees and workers.

  • Pakistan

  • Pakistan stated on July 17 that the mediation efforts have not been abandoned between Iran and the US despite the ceasefire’s collapse, with Pakistan Foreign Office spokesperson Tahir Andrabi acknowledging the environment is now dominated by “the logic of escalation” but maintaining the diplomatic initiative remains relevant. Pakistan Prime Minister Shehbaz Sharif spoke separately with Qatari leadership and Iranian President Pezeshkian on July 10, urging restraint. At this point, Islamabad is managing a two-front diplomatic strain. It continues positioning itself as a mediator even as talks stall, while its western border with Afghanistan stays volatile.

Global Systems

  • Strait of Hormuz
  • Three days are equal to three weeks. On July 13, calm returned as oil prices matched pre-war levels and shipping re-established itself, only to collapse on Tuesday when Iran attacked three tankers, prompting potential US strikes, revoking an oil license, and lowering transit ratings to “severe”. Tehran’s strategic timing, from Khamenei’s funeral to the US midterms, conveys calculated influence rather than panic. The MoU survives only on paper; Hormuz remains contested, and India’s energy calm stays borrowed.

Defense & Security

  • War Tactics & Strategy
  • The US and Iran exchanged fire for six consecutive days through July 16, with the American strikes hitting Iranian command centres and missile sites while Iran targeted US bases in Gulf countries, both sides fighting over control of the Strait of Hormuz. Washington reimposed its naval blockade on July 14, and CENTCOM used armed sea drones in combat for the first time. The Corsair strikes invert Iran’s own “swarm” doctrine of small, high-speed boats striking shipping and naval vessels, using stealthy autonomous hulls against fortified Iranian infrastructure instead. Iran responded with drone waves causing material damage in Kuwait, while pairing tanker interdiction, blockade enforcement, and GPS interference to sustain pressure on both sides of the strait.
