After the sinking of one of their battleships, South Korea is playing loud K-pop across the border to the North:

S.Korea recently put up loudspeakers in 11 locations along the tense border to resume broadcasts that had been suspended in 2004. The installation of the loudspeakers amounted to “a direct declaration of a war” and a “flagrant violation” of the inter-Korean declaration for peace and reconciliation signed in 2000, the North’s statement went on. “Therefore, the revolutionary armed forces of the DPRK will launch an all-out military strike to blow up the group’s means for the psychological warfare,” it said. The North has repeatedly threatened to strike down the loudspeakers if Seoul goes ahead with the broadcasts.
