1969 was a year, much like out present era, in which many in the USA realized that we were trapped in a war which had no real purpose, could not be won, and from which we could not extricate ourselves. (The war went on for another mindlessly obscene six years!)

A major challenge of the era was how to keep one’s life from being engulfed by the tide of arrogance and stupidity represented by the war that would not stop, how to keep one’s heart from dying of grief. That was the context in which Crosby, Stills and Nash wrote and performed this song.
