The North Koreans, however, have not forgotten. Sixty years after the end of the Korean War, the country is marking the milestone anniversary with a massive celebration tomorrow for a holiday it calls "Victory Day", even though the two sides only signed a truce, and have yet to negotiate a peace treaty.
Signs and banners reading "Victory" line the streets of Pyongyang, the North Korean capital. The events are expected to culminate with a huge military parade and fireworks, one of the biggest extravaganzas in this impoverished country since leader Kim Jong Un took power in late 2011.
In some ways, war today is being waged outside the confines of the now-outdated armistice signed 60 years ago.
The disputed maritime border off the west coast of the Koreas is a hot spot for clashes. In 2010, a South Korean warship exploded, killing 46 sailors; Seoul blamed a North Korean torpedo. Later that year, a North Korean artillery attack on a front-line South Korean island killed four people, two of them civilians.

Sixty years on, as both Koreas and the United States mark the anniversary tomorrow, there is still no peace on the Korean Peninsula.
The two sides don't even agree on who started the war.
Outside the North, historians say it was North Korean troops who charged across the border at the 38th parallel and launched an assault at 4 am on June 25, 1950.
