From The American Presidency Project, Proclamation 10235—National Korean War Veterans Armistice Day, 2021:

“The United States and the Republic of Korea are allies with a long history of shared sacrifice. In a call to defend freedom and democracy abroad, 1.8 million Americans joined the fight to protect our Korean Peninsula allies from the communist regimes in North Korea and The People's Republic of China. In 1953, after 3 years of violent combat and millions of casualties, an armistice was signed by representatives of the United States, The People's Republic of China, and North Korea. The armistice made possible the exchange of prisoners of war as well as an opportunity to negotiate a peaceful settlement. Almost 70 years later, that settlement still has not been reached, and the Korean Peninsula remains divided along the 38th parallel. Yet, the Republic of Korea has grown into a thriving, vibrant country, and the enduring relationship between our two nations has flourished through decades of peace. Today, we take this opportunity to honor, remember, and pay tribute to the Korean War veterans who fought to defend those universal values and freedoms that the people of South Korea enjoy today.”
