Iran’s new military plan: regime survival through regional escalation - report
Iran has adopted a high-risk 'mosaic defense; strategy, expanding attacks on Gulf states and key trade routes to ensure regime survival after last year’s war with Israel
After last year’s devastating conflict with the United States and Israel, Iranian leaders have reportedly adopted a major strategic shift aimed at expanding the war across the Middle East to secure the regime’s survival, according to the Wall Street Journal.
Previously, Iran responded to foreign strikes with limited, targeted reprisals. The new doctrine abandons that approach, aiming instead to escalate the conflict regionally, particularly against Gulf Arab states and critical economic infrastructure. The goal is to disrupt the global economy and pressure Washington into shortening the war.
This decision followed the twelve-day war with Israel in June 2025, during which Israeli and U.S. strikes eliminated senior Iranian military leaders, destroyed key air defense systems, and severely damaged nuclear facilities. In response, Supreme Leader Ali Khamenei—before his elimination early in the current conflict—activated a strategy designed to maintain continuity even if top commanders were neutralized.
Central to this approach is the so-called “mosaic defense” doctrine: a decentralized military structure in which the Islamic Revolutionary Guard Corps (IRGC) operates through multiple regional command centers. Each center can conduct operations independently, allowing local commanders to continue fighting even if national leadership is incapacitated. This makes the military apparatus more resilient to targeted strikes.
Following the adoption of this doctrine, Iran quickly expanded hostilities, launching missile and drone attacks on the UAE, Qatar, Bahrain, and critical energy and port infrastructure. The strategy also aims to disrupt key trade routes, including the Strait of Hormuz, through which roughly one-fifth of the world’s oil passes.
Analysts cited by the Wall Street Journal suggest that Tehran’s calculation is to make the conflict costly enough for all parties to force the U.S. and its allies into a diplomatic resolution.
However, the plan carries enormous risks. By escalating attacks on regional states and international economic interests, Iran could provoke a broader coalition against itself. Despite prior military losses, Iranian forces retain the capability to launch drone and missile strikes, maintaining their influence over the ongoing conflict.
For Iranian leaders, the immediate priority remains unchanged: the survival of the regime, even if it requires a major regional escalation.
