SEOUL, South Korea (AP) – U.S. President Joe Biden will meet South Korean President Yoon Suk Yeol this week as the allies face a growing threat from North Korea’s nuclear weapons and missile program. The North may highlight the threat with a major weapons demonstration, even as it grapples with a COVID-19 outbreak that is ripping through its unvaccinated populace. Both U.S. and South Korean intelligence officials say it’s possible that North Korea will conducts a ballistic or nuclear test around Biden’s visit to South Korea and Japan. While North Korea is expected to be at the top of the agenda when Biden and Yoon meet in Seoul on Saturday, it’s unclear whether the meeting will produce a meaningful new approach in handling the nuclear threat.
