Iran is already demonstrating how to exhaust a supply of $4M patriot missiles with $50k drones. Broadly speaking, chaos is cheap when asymmetrical power is available and successful and soft, undefended targets are numerous and readily available. The cost to defend everything at once is untenable, and in some cases, it is almost impossible to defend the target at all (artillery against an LNG loading facility, for example).
Cyberattacks can also be performed from anywhere cost effectively. I certainly hope we haven’t underfunded and crippled CISA.

They're weak spots and an unfortunately, as you accurately point out, those systems are largely what is the back end of so much of our critical infrastructure," he said.
