Iran’s recent missile and drone attacks across the Gulf mark a dangerous expansion of the Islamic Republic’s regional war. The Islamic Republic appears to be widening the battlefield beyond American and Israeli targets by pressuring Gulf Cooperation Council states that had previously attempted to maintain neutrality in the conflict. This strategy risks transforming potential mediators into adversaries while strengthening regional security cooperation between Israel, the United States, and Sunni Arab states. Iran’s escalation reflects internal vulnerabilities within the clerical regime, including the economic crisis, political repression, and growing domestic unrest. By projecting power externally, Tehran seeks to reinforce its ideological authority while diverting attention from internal instability. Ultimately, Iran’s expanding aggression may achieve the opposite of its intended goal by accelerating the formation of a broader regional coalition that is determined to contain its ambitions and restore stability to the Middle East.
