After Yoon's statement the military said activities by parliament and political parties would be banned, and that media and publishers would be under the control of the martial law command.
Yoon did not cite any specific threat from the nuclear-armed North, instead focusing on his domestic political opponents. It is the first time since 1980 that martial law has been declared in South Korea.
That's uh pretty explicit. Not quoted are two other key facts;
In South Korean law parliament can end Martial Law with a simple majority vote.
They did that vote immediately.
The Army "attempted" to take the parliament building but was rebuffed by staff members and fire extinguishers.
Y'all, those soldiers were not on board with this idea. And this is all vitally important because South Korea was a dictatorship for most of the cold war. This is absolutely an attempt to reinstate that.
