North Korea cut off its hotlines with which nation in June 2020:

🧠 Explanation:

In June 2020, North Korea severed all communication hotlines with South Korea, escalating tensions on the Korean Peninsula. This decision followed deteriorating relations, marked by stalled denuclearization talks and North Korea’s frustration with South Korea’s handling of defector activities, such as sending propaganda balloons.
