If the NKs flip a missile our way (and I include Japan in that statement because I live here) I do not want the U.S. Forces or JSDF commanders gabbling away on the phone to the White House or the Prime Minister's office.
Any unannounced missile coming your way is, by definition, hostile and should be destroyed.
You can bet it doesn't have a bouquet of flowers in it's warhead bus.
Off topic: Ronin - good movie.
