개가 짖어도 기차는 달린다

Etymology
Literally "The dog(s) bark(s), but the train speeds on." Partial.

Used commonly in both North and South Korea since at least the 1990s. In South Korea, the proverb is most famously associated with (and sometimes mistakenly considered an invention of) President, one of the country's first democratically elected leaders. In 1993, Kim disbanded the organization that had been the backbone of the preceding military dictatorship. This was Kim's response when he was asked if he did not fear retaliation from the generals of the Hanahoe.

Proverb
