In the song "what's going on," how does the singer show that society is going through troubled times during the 1960s and 1970s?

The hit song "What's going on" shows the turmoil faced in American society during the 1960's and 1970's.

This song, released in 1971, references how "war is not the answer." This lyric is a direct reference to America's long time involvement in the Vietnam War.
By the time this song is produced, America had been involved with Vietnamese affairs for almost a decade and have sent thousands of young American men to this country only to die for a cause that many of them did not believe in.
Also, the singer references how " We've got to find a way to bring some loving today." This can refer to the escalated racial tensions between African-Americans and whites during the Civil Rights movement.
