Won Gon Park, Head of the EAI North Korea Studies Center, assesses that North Korea's trash balloon campaigns are a direct response to South Korean leaflets that challenge the legitimacy of Kim Jong Un's claim to the "Paektu Bloodline." Additionally, Park points out that North Korea's decision to launch 10 short-range ballistic missiles (SRBMs) simultaneously was a demonstration of its military capabilities against South Korea and the U.S., especially following a joint military exercise that included undetectable stealth jets. However, Park notes that these balloons are not a security risk for South Korea, and the KN-25 missiles are insufficient to challenge the air superiority of the South Korea-U.S. alliance.
