seems hiroshima and nagaskai weren't harsh enough lessons...
while NK may not have a nuclear bomb per se, i'm sure they could use some missles and make a "dirty" warhead.
and to trot out this oldie....
"war never determines who's right... only who's left."
i'd sure as hell oppose any US intervention/assistance if Japan actually declares war - which i seriously doubt, anyway, vox populi aside.
