ANOTHER war of words has erupted between Pyongyang and Washington. This time the statements emanating from both sides are more bellicose than usual. The latest round of verbal hostilities started after the hacking attack on Sony Pictures. North Korea has been vehemently criticising the Japanese owned company which has its headquarters in the United States, for producing the movie “The Interview”. The movie, purportedly a comedy, shows the assassination of the current head of state of North Korea, Kim Jong- un.
