I believe I heard on the radio today that NK is believed to have 60 nukes. I thought it was 10-20. They could inflict a lot of damage with 60 of them even if only a handful got through.
when have they ever tested these missiles...not easy wedding a warhead to a missile then having it detonate properly...not a smart tactical move with at least 2 Trident “city killers” off your coast.
