In theory; in practice however, there's been rocket fire from Gaza towards Israel where the offence was literally a metallic tube with a bit of TNT at a cost of about $800 per rocket [0] while the defence was $100,000+ per interceptor [1]. This has been going on for years, and as far as I'm aware there was no depletion observed.

I don't know the economic numbers off the top of my head but I have to imagine it's hard to find Israelis who think they're spending too much money on rocket interceptors.

If Mexico as a nation state intentionally launched a single offensive rocket from Juarez to El Paso, we would just invade.

Interceptors are an unnecessary expense in the ways that they have been used in the past 15 years.
