While not the time for it, I can see Israel using it, and seconds after a successful defense of an inbound sending over one of their own. Maybe do it during an Iranian missile test.
Let Iran know that anything that flies towards Israel will be shot down and countered. Make that standard operating procedure.
If the feds won’t buy this stuff to protect our cities (say, from cruise missiles launched offshore), then maybe the state National Guards ought to authorize their purchase.
(If Washington won’t do it, maybe self-reliance will again become necessary.)
