The Korean War has been called “the Forgotten War” in the United States, where coverage of the 1950s conflict was censored and its memory decades later is often overshadowed by World War II and the Vietnam War.

But the three-year conflict in Korea, which pitted communist and capitalist forces against each other, set the stage for decades of tension among North Korea, South Korea and the United States.

It also helped set the tone for Soviet-American rivalry during the Cold War, profoundly shaping the world we live in today, historians said.
