US Marines Deploy; Hormuz Oil Security Challenged

This significant military operation, according to Mark Cancian of the Center for Strategic and International Studies, acknowledges that aerial bombardment alone cannot adequately protect commercial shipping from Iranian drones and missiles. The deployment aims to secure the vital strait, a conduit for one-fifth of the world's oil and liquefied natural gas, which has seen oil prices surge above $100 a barrel due to Iranian threats. Marines, part of a rapid-response force from Japan, are expected to arrive in weeks.

Their likely mission involves seizing small islands to establish air-defense systems, creating a protective "dome" for convoys, a multi-branch effort involving naval escorts and air cover. While seizing Kharg Island, an Iranian oil hub, is a possibility, securing the strait is prioritized.

However, the strait's narrowness (33 km) and proximity to Iranian territory make it highly vulnerable to inexpensive Iranian weapons like drones, small boats, and anti-ship missiles. Cancian believes 2,500 Marines are insufficient, and despite President Trump's appeals, key allies like Germany and the UK are reluctant to commit forces, citing a desire to avoid escalating the conflict.

This situation highlights a perceived lack of preparedness by the U.S. military for such a contingency.
