It could take three to eight years for the U.S. to replenish its stockpile of high-altitude missile interceptors after the military launched nearly 14% of its arsenal during last month’s conflict with Iran, according to a new report by the Jewish Institute for National Security of America.
12 days. If we assume the a consistent rate, which isn’t a good assumption probably, then it would take 85 days to completely deplete the stockpile. Well technically less than that due to 14% already wasted.
In other words the existence of Israel depends on a war that lasts less than 3 months, perhaps shorter.
