Iran managed to penetrate Israel's air defense systems during the "12-day war" by changing launch tactics and identifying "gaps" in Israeli defense through "trial and error," The Wall Street Journal reported, quoting air defense missile experts who analyzed images of missile fragments and open-source information. According to the experts, Tehran began launching more sophisticated and longer-range missiles from a "variety" of locations deep within Iran, and they claim the ayatollah regime successfully timed the attacks and methods, as well as the distribution of targets in Israel. "As the war progressed, fewer missiles were fired, but more hit their targets," the report stated.
