Will 2 Korean's go for WAR?

Tension rise between 2 Koreans. North Koreans said they no longer bound by the armistice which ended the 1950-53 war on peninsula and no guarantee on the legal status of 5 South Korean island near disputed border in Yellow Sea. Neither would it guarantee the safe passage of US and South Korean vessels in the area. North Korean assumed a decision to join a US-led anti-proliferation initiative as a declaration of war by South Korean. I believe the statement is very strong an-indication for war decalaration in near future.
