China often uses its state run papers to vent. Events and decisions that bother the Chinese government get put on blast on these newspapers, but it doesn't mean China will do anything about it. China also uses these same papers to attack North Korea, but the actual state of affairs between China and North Korea don't change much.
The attack launched by North Korea seemed so childish to me. I felt as if I was hearing about a mischievous little child that got away with a prank, only to stand there dancing while screaming na na na na na. What's really troubling, is that you can never tell how far a person with this kind of mentality would go. I mean could we be looking at war with this country over something of equal significance as a comedy? This is quite worrisome IMO.
