Experts Left to Decipher Kim Jong Un's Latest Letter to South Korea Kelly Kasulis SEOUL, SOUTH KOREA - North Korea is sending mixed messages to South Korea in the age of the coronavirus: Earlier this week, Pyongyang conducted its first short-range ballistic missile test in more than three months, then broke its hostile silence by sending well-wishes to the South Korean president. North Korean leader Kim Jong Un penned a letter to South Korean President Moon Jae-in Wednesday, expressing concern for Moon's health and wishing him luck in battling the nationwide COVID-19 outbreak. South Korea has at least 6,284 confirmed cases of the virus as of midafternoon March 6, and 42 deaths. Meanwhile, North Korea claims to have zero cases. Pyongyang's latest mixed signals are perplexing for North Korea analysts, who can only guess why Kim Jong Un would both conduct hostile launches and send warm regards in a matter of days. "It's strange behavior. I mean, it's weird, and I just can't fully explain it," said Peter Ward, a researcher on the North Korean economy and writer for NK News. "The missile test is probably a signal of displeasure on the alliance front with the U.S., and the letter to Moon is more about setting corona-related mood music. But I'm not entirely sure what's going on -- it doesn't really make sense to me." .
