South Korea did what it had to do to protect its government from a coup by a dictator.
Why couldn’t the US have done the same?

South Korean President Yoon Suk Yeol has so far refused to cooperate with investigators after he was arrested for questioning on Wednesday, the country’s anti-corruption agency said.

Yoon is wanted for questioning in multiple criminal investigations related to his martial law decree last month, including over accusations of leading an insurrection – a crime punishable by life imprisonment or even the death penalty.
