The president's ultraconservative supporters believe that the country has been overrun by North Korea sympathizers conspiring to destroy South Korea’s freedoms.

In declaring martial law early last month, Yoon used similar language, citing the need to “eradicate pro-North Korean forces.” He later defended the move as a temporary measure to warn his opposition rivals, whom he accused of obstructing governance. Critics, however, viewed the declaration as an authoritarian overreach.

A prolonged period of uncertainty over the fate of impeached South Korean President Yoon Suk Yeol and a botched attempt to arrest him are giving oxygen to his backers and reviving support for his troubled party.
