Iran’s air defenses (AD) excelled against IDF during Israel’s strikes on 25/26 October 2024. IDF encountered “an unknown air defense system”—probably advanced anti-stealth technology—and aborted the bombing mission. If stealth technology was defeated, the foundations of US/NATO/IDF air superiority collapses. Focus here, however, is on implications for Iranian national security. If Iran does indeed have effective AD systems, while Israel’s AD systems can be penetrated by IRGC (twice proven), Iran can open the gates of hell for Israel.
