Kim Yo Jong, the sister of the North Korean leader and undoubtedly one of his most trusted advisors, has been very active in the realm of foreign policy recently. Within just 10 days, she made four significant statements on various international issues. 

On July 10 and 11, she slammed the U.S. for conducting reconnaissance flights within North Korea's exclusive economic zone (EEZ). Then, on July 14, she vehemently opposed the U.S. decision to convene a U.N. Security Council (UNSC) meeting following North Korea's intercontinental ballistic missile (ICBM) launch. Finally, on July 17, she expressed outrage about the U.S. dispatch of a nuclear missile submarine and other strategic assets to South Korea.
