now the Israeli narrative is that Iran launched c. 180-200 missiles and Israel intercepted the "vast majority" (around 80%) of them
80% of 180 = 144 intercepts
even assume 1:1 ratio of interceptors to missiles (which is very rare and risky), that means Israel fired > 100 Arrow interceptors! Each one costs $3-5 million...
Prior to April 2024, Israel had c. 300 Arrow interceptors in total. It used at least 50 in the April attack and now it used another 100+. So half of its entire inventory of Arrow interceptors is likely depleted.
And those were just the two opening salvos from Iran. Another two rounds like that and Israel will have no Arrow interceptors left... Hence why Israel is so reliant on US/Western assistance and 'shock and awe' tactics to avoid long term war.
