Newsweek reported that the biggest problem plaguing President Yoon Suk Yeol is not North Korea but domestic matters.

In an interview with the U.S. weekly released on Friday, President Yoon emphasized the need for “structural reform” in the country. 

Yoon said that the previous governments feared unpopular policies and they feared that they might lose the election, so they delayed what should have been done, but the country cannot put it off forever. 

Newsweek said that while the threat of new conflict with the nuclear-armed North Korea has long loomed across the armistice line, the South's domestic problems are growing—from its record-low birthrate, the strains on its health care system, worries over the labor force to education. 

The weekly said that Yoon, who is reaching the halfway point in his five-year term, is seeing his approval rating falling to record lows and facing criticism due to controversies surrounding his wife.

President Yoon, however, expressed his intent to push through reform plans, saying that he has no time to think about his approval rate and he should get things done within his presidency.
