TOKYO -- South Korean President Yoon Suk-yeol has already made big waves barely a month into office, especially when it comes to national security.
When North Korea fired eight short-range ballistic missiles into the ocean on June 5, South Korea fired eight surface-to-surface missiles together with the U.S. the very next day -- a drastic shift from Seoul's more conciliatory approach under former President Moon Jae-in.
