President Park Geun-hye called for an "airtight" security posture against North Korea from South Korean soldiers and other officials on Saturday, viewing the North's recent charm offensives as a possible prelude to imminent military provocations. "In India, Park ordered the (South Korean) defense minister and other security-related ministers to make more efforts to keep an airtight security posture against (potential) provocations at a time North Korea is conducting a flurry of propaganda offensives," a presidential official told reporters in New Delhi, India, asking not to be named.
