President Yoon Suk Yeol’s stunning martial law declaration lasted just hours, but experts say it raised serious questions about his ability to govern for the remaining 2 1/2 years of his term.

Republic of Korea President Yoon Suk-yeol is facing impeachment over his declaration of martial law in the country on Tuesday night, an order he was forced to withdraw within six hours of announcement as ROK lawmakers unanimously voted against it.
