As South Korean activists prepare to send political pamphlets across the border on Monday, North Korea made it clear today that they will respond with a civilian attack. The pamphlets, some stuffed with dollar bills, criticize the North Korean government, and will be air-lifted by balloons to reach the impoverished citizens of their neighbor nation. But North Korea’s state news agency has announced that if the human rights activists follow through on this plan, they will retaliate with a “merciless strike” against South Korea’s tourist region.
