# Iran Prepares New Operational Response Amid Escalating Maritime Attacks Tehran warns of devastating retaliation as commercial shipping faces increased regional security threats. - **Source:** [US Top News and Analysis](https://brifing.si/source/635540e9-943e-450d-ae52-ae0bfe3b67eb) - **Published:** 2026-10-18 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/67b96478-25b2-40fe-9c42-97f9f9c17cec ## New Iranian Security Strategy Mohsen Rezaei, secretary of Iran's Supreme National Security Council, announced a new operational plan for potential U.S.-Israeli attacks. This strategy explicitly deviates from past conflict rules, aiming to be more devastating than previous engagements in June 2025 and February. Tehran emphasizes that its military response will be unpredictable and significantly more severe. ## U.S. Stance on Engagement President Donald Trump stated he does not intend to deploy ground troops or utilize nuclear weapons against Iran. Addressing reports regarding the potential use of the GBU-43/B Massive Ordnance Air Blast, Trump reaffirmed U.S. nuclear superiority without confirming specific tactical plans. Meanwhile, Foreign Minister Abbas Araghchi maintains that Iran remains open to diplomatic dialogue. ## Maritime Security Incidents Surge Commercial vessels near the Arabian Peninsula report frequent hostile encounters. On Sunday, a tugboat northeast of the UAE sustained damage from two unknown projectiles. Previously, a liquefied natural gas tanker southwest of Yemen engaged in a firefight with a small skiff, while another tanker northeast of Saudi Arabia was struck by a rocket-propelled grenade. ## Energy Infrastructure Under Fire Saudi Arabia’s energy infrastructure faces direct threats from Iran-allied Houthi militants. A military spokesman confirmed interceptions of missiles targeting the Yanbu oil export terminal and drones over Riyadh. Additionally, an Aramco administrative building in Dhahran was hit during a Tuesday attack, highlighting the vulnerability of critical regional energy assets to ongoing regional instability. ## Global Oil Market Volatility Crude oil prices experienced sharp increases as regional tensions intensified. Brent futures reached $110 per barrel, marking the highest level since May, before settling at $109.86. U.S. West Texas Intermediate also climbed 3.5% to $101.41. These price movements reflect investor anxiety regarding potential supply chain disruptions in the critical Arabian Peninsula maritime corridor. ## Historical Conflict Context The current rhetoric references past military engagements, specifically the 12-day and 40-day wars. Iranian officials use these historical benchmarks to frame the potential scale of their new operational plan. By citing these specific durations, Tehran signals that its current defensive posture is designed to surpass the intensity of previous confrontations with Israeli and U.S. forces. ## Operational Shift in Tactics The shift in Iran's operational plan suggests a move away from conventional engagement patterns. By explicitly stating that the new plan will not follow familiar rules, Tehran aims to create strategic ambiguity. This approach forces adversaries to reconsider the risks of further military adventurism, as the threshold for Iranian retaliation remains intentionally undefined and fluid. ## Implications for Regional Stability The combination of maritime attacks and threats to energy infrastructure creates a volatile environment for global shipping. As oil prices react to these security breaches, the intersection of geopolitical conflict and energy logistics becomes increasingly precarious. Stakeholders must monitor the balance between Iran’s readiness for dialogue and its stated commitment to aggressive military deterrence. ## Sources covering this story - https://www.cnbc.com/2026/10/18/iran-us-war-rezaei-operational-plan-shipping-attacks.html — --- _Summary written by Brifing from the original reporting.
