On Wednesday, South Korea's state media reported that North Korea had launched more than 150 balloons filled with excrement and garbage over its border with the South. The move prompted officials to advise residents to shelter inside.
South Korean bioterrorism response squads reportedly found items including cigarette butts, plastic water bottles, and compost in the balloons that were released by timers in the South's airspace.
The ridiculousness of the waste-filled balloons aside, Pyongyang's potential to integrate balloons with modern warfare tactics is quite high. They offer advantages in intelligence, surveillance, and reconnaissance, operating at altitudes and capabilities for wide-area monitoring. Historically used for propaganda and other purposes, balloons are cost-effective tools in the modern geostrategic environment and the North's actions must be closely monitored.
For some time now, South Korean activists have been sending anti-Kim Jong-un pamphlets into North Korea via balloons, despite a ban. While they also send balloons carrying vitamins and painkillers, propaganda is a key motive — especially against North Korea’s nuclear program. South Korean President Yoon Suk-yeol’s government is supportive of such activists. The North is now answering them with both proportionality and wit.
