North Korea has kept the surrounding region on edge in recent weeks primarily by using its weapon of choice in times of warmongering: its state-run news agency.
The Korean Central News Agency, a massive wire service, serves as the primary mouthpiece for the North's repressive government, lauding upticks in factory production, documenting the arrival of floral baskets for the ruling Kim dynasty — and occasionally warning about possible nuclear strikes on its neighbors.
But the agency also serves a broader purpose, setting the mood for a nation — and changing that mood at the direction of the nation's leaders.
