Dozens of Korean Americans penned an open letter urging U.S. President Joe Biden to officially end the 70-year-long Korean War on Wednesday.

The letter, which was signed by 71 individuals including university professors, artists, activists and celebrities, calls for a “peaceful resolution” to the Korean conflict, which technically drags on under a ceasefire agreement signed in 1953. Roughly 2.5 million people are thought to have died in the Korean War, depending on the estimate, and several other lethal skirmishes have broken out since.
