The United States was still the "biggest threat and potential invaders" toward the Democratic People's Republic of Korea (DPRK) with its anti-DPRK policy "having no slightest change," said a commentary carried by the official Rodong Sinmun daily on Monday.

The article scolded the U.S. on its build-up of military force around the DPRK, accusing it of making preparations for an invasion against the DPRK. It said that the U.S. had branded the DPRK as a "security threat" in a just broadcasted report on intelligence strategy. The purpose of the strategy was to snuff out the DPRK so as to control the whole Korean peninsula, it added.

It said that the hostile approach toward the DPRK made it impossible to improve the bilateral ties. It was "totally appropriate" for the DPRK to develop nuclear deterrence under such situation, it noted.
