According to NBC News, a senior Israeli official admitted that the interception rate of the Israeli Defense Forces against Iranian missiles has plummeted from 90% to 65%.
This number can be interpreted in three ways:
Firstly, as belligerents, no one admits failure. To comfort the public and boost morale, Israel may overstate its achievements. The publicly stated 65% interception rate is actually unattainable.
Secondly, the cost of defense is too high. Currently, Israel mainly uses the "Arrow" anti-missile system to intercept missiles, with each interceptor costing $3 million to intercept one missile. Such high costs are unsustainable for Israel.
Thirdly, Iran's missiles have been upgraded. Medium and long-range and supersonic missiles cannot be intercepted by Israel's "Iron Dome". Therefore, it is necessary to upgrade the defense system, but the newly upgraded defense system fails to meet the defensive needs.
