The Korean War started in 1950. An armistice was agreed in 1953, but there has never been a peace treaty.?
'An armistice is a formal agreement of warring parties to stop fighting. It is not necessarily the end of a war, since it may constitute only a cessation of hostilities while an attempt is made to negotiate a lasting peace.'
The question is why the US is saying that the war in Afghanistan is the longest war in US history?
Sorry about that. I got a bit 'carried away'.
