I want to know the answer to the following question:
Why is North Korea insisting that the 1953 armistice was violated?
All the background I'm provided with is that "On 30 March 2013, North Korea stated that it had entered a "state of war" with South Korea and declared that "The long-standing situation of the Korean peninsula being neither at peace nor at war is finally over".". Is that enough to answer the question?
Answer: no
