The US, Gulf states, and Israel are quickly running out of missile and drone interceptors.
The US also used over 25% of their long-range Tomahawks, possibly 45% of their JASSMs, and over 25% of their ATACMS.
By mid-May, the US could be out of many of these weapons.
The US has failed to build sufficient manufacturing capability. It will take many years to replace these munitions.
The US will have to use dumber bombs and take more hits on the defense if the war goes on.
