Internet reports that on the 20th local time, Israel Defense Forces Chief of Staff Zamir issued a video speech saying that Israel must prepare for "a protracted war against Iran" to "eliminate a threat of this magnitude." Zamir said Iran has been developing a clear plan for years to destroy Israel. In recent months, this plan has reached a point where there is no turning back, and its capabilities have reached a practical level. Zamir said that when Israel launched the operation, Iran had about 2500 ground-to-surface missiles with extremely high production capacity. Based on this calculation, Iran's missile inventory will reach about 8000 in about two years. Iran's development of ballistic missiles, the expansion of proxy forces in the Middle East and the advancement of its nuclear program "force us to strike proactively." He said that the Israeli army has been preparing for the operation for many years and is launching it now because the convergence of operational and strategic conditions has reached the best opportunity.
