The Korean War began 25 June 1950, when North Korean armed forces invaded South Korea. The war’s combat phase lasted until an armistice was signed 27 July 1953.
When is a war not a war? For the Korean War, the answer is not always clear. This year, 2013, marks the 60th anniversary of the ceasefire of a war that not everyone describes that way. It had ambiguous beginnings, more than 20 participating countries, and still no formal end.
