There is apparently some discussion about parking some THAAD missiles along the west coast to protect against the likes of a Nork missile. The THAAD isn’t a full-up anti-ICBM system, but it’s the best the US currently has for land-based systems. It’s also the only missile in operation that has an important subsystem (the igniter) designed by *me.* So there.
There is, of course, no actual money for this.
