Korea's war of words

The North and South Koreans have clashed at sea.
The South (goodies) opened fire on the North's (baddies) vessel when it strayed into their waters.
Unbowed the North retaliated, causing the South's ships to be 'flurried', according to their official news agency KCNA.
Say what you like about the North Koreans but they certainly talk the florid talk.
Here's a warning to the USA after a missile test near Hawaii.
'They had better behave prudently, bearing in mind that their adventurous scenario for a preemptive attack on the DPRK is nothing but a foolish one bringing them self-destruction.'
