Arriving at the Korean War Veterans Memorial in Washington on Saturday
President Barack Obama laid a wreath, to honor the veterans.
The president was there to commemorate the 60th anniversary of the Korean War ceasefire that divided the peninsula into two.
Speaking in front of about 5-thousand people, including veterans of the war, President Obama declared that the war was a victory for South Korea and the U.S.
"When 50-million South Koreans live in freedom--a vibrant democracy, one of the world's most dynamic economies, in stark contrast to the repression and poverty of the North---that's a victory, that's your legacy."
The Korean War broke out in 1950 and continued on until 1953, when it came to a halt with an armistice.
Up to 2-million Koreans. and more than 36-thousand American troops were killed.
In his speech, President Obama spoke mostly on honoring the veterans and the importance of remembering the Korean War as a "forgotten victory," and not a "forgotten war" as it is commonly called, having come right after the Second World War.
"Among many Americans there was, it seemed, a desire to forget"
President Obama is the first sitting American president to attend an official Korean War Armistice Day event.
A Korean delegation, sent by President Park Geun-hye, was also there, led by representative Kim Jung-hoon of the ruling Saenuri Party.
"The freedom and the prosperity we enjoy today are built on the assistance we received from the U.S., and the noble sacrifice shown by the U.S.-led UN coalition 60 years ago."
