dogs that bark won't bite. then again, nobody knows if this also applies to insane dogs with god complexes.
in all seriousness, I think america doesn't really have to worry about nuclear strikes. I doubt that NK has nearly enough ressources to bomb all over the US, and I also think that the US should have more than enough measures against eventual nuclear strikes.
the ones who should be worried are SK and Japan. they are both within reach and most likely couldn't prevent an nuclear strike in time. but as long as the NK regime has not gone completly nuts, they won't do anything because they will most likely die a bomby death send by the US if they decide to launch a nuclear strike.
