Concerns are growing over Iran's rapidly advancing missile capabilities after former Pentagon adviser Theodore Postol warned that some of Tehran's newest missiles may be extremely difficult to intercept. Postol said Iran's improved missile accuracy, larger warheads, and enhanced strike capabilities have changed the strategic balance in the region. Former Israeli Navy commander Eliezer Marom also acknowledged the growing threat, claiming Iranian missile barrages have caused significant damage inside Israel. As Iran continues expanding missile production and technology, questions are mounting over the effectiveness of current missile-defense systems and the future of regional security.
