Is Kim Jong-un Really Planning an Attack This Time?

North Korea fired hundreds of artillery shells in waters near South Korean border islands on Jan. 5. Last week, it said it no longer regarded the South as inhabited by “fellow countrymen” but as a “hostile state” it would subjugate through a nuclear war.

On Friday, it said it had tested an underwater nuclear drone to help repel U.S. Navy fleets.That new drumbeat of threats, while the United States and its allies have been preoccupied with the wars in Ukraine and the Middle East, has set foreign officials and analysts wondering whether the North’s leader, Kim Jong-un, has moved beyond posturing and is planning to assert more military force.

Analysts in China, North Korea’s most vital ally, were also deeply skeptical that Mr. Kim would go to war unless the North were attacked. Prof. Shi Yinhong, at Renmin University in Beijing, asserted that the North’s leadership, not being irrational, ultimately acted out of self-preservation — and that starting a war would work against that goal.

Others noted that the North could assert itself militarily, including through smaller conventional strikes and bolder weapons testing, without necessarily triggering a deadly response.

“There are many rungs of the escalation ladder that North Korea can climb short of all-out war,” said Victor Cha, a Korea expert at the Washington-based Center for Strategic and International Studies. “Kim is not that confident in his capabilities to deter U.S. reaction if he were to do something rash.”
