Pyongyang considers Seoul to be its “most harmful and unchangeable enemy,” the leader has said
Pyongyang must be prepared to seize South Korean territory in the event of an “emergency,” North Korean leader Kim Jong-un has said.
In a speech marking the 76th anniversary of the founding of the North Korean Army on Friday, Kim praised the military for “firmly protecting the sovereignty and dignity of the country” from “imperialist military threats, blackmail, and the risk of war.”
[Kim] said his country has “summarized the history of our people’s division and confrontation and defined [South] Korean puppets as the most harmful and unchangeable enemy” of Pyongyang.
Against this backdrop, Kim stated that in the event of an “emergency,” North Korean policymakers had “made a national decision to occupy and pacify [South Korean] territory.”
Last month, Kim also called on the national parliament to label South Korea the “number one hostile country.”

Citing US officials, the New York Times reported in January that Washington is worried that North Korea could “take some form of lethal military action” against Seoul. The paper’s sources, however, doubted that Pyongyang would risk anything resembling a full-scale attack.

This doesn't read to me like the DPRK has any plans to take any military action in the near term, Kim is simply reiterating that the DPRK must remain prepared to do so should a big opportunity arise or the US crosses a red line.
