Aug. 15 marks South Korea’s 75th Liberation Day — a national holiday that commemorates the peninsula’s freedom from Japanese colonial rule.

Last year’s Liberation Day came with big promises: South Korean President Moon Jae-in pledged to work towards reunification by 2045, a century after the peninsula’s original liberation.

“I pledge to solidify the foundation so that we can successfully host the joint 2032 Seoul-Pyongyang Olympics and stand tall in the world as one Korea by achieving peace and unification by 2045,” Moon said.

Even if Moon’s dream deadline is realized, though, 25 years is a long time to wait
