Time to base at least 2 x 61 missile MK-41 launch cells used on cruisers filled with ABM versions (102 missiles) at Barking Sands to compliment that new SPY-6 extended range radar.  This to ensure they can take multiple shots at  any inbound ballistic missiles from North Korea and create an impenetrable barrier, so it would be futile to do so again.  Yes, it would be expensive, but to protect billions upon billions of dollars of infrastructure, population, and critical military bases in Hawaii would be a no-brainer and worth it.  Even with the other type of interceptors based in Alaska, it would be smart to have this additional layer of defense.
