How did events happening in one place affect other places in the 1960?

The 1960s started off as the dawn of a golden age to most Americans. On January 20, 1961, the handsome and charismatic John F. Kennedy became president of the United States. His confidence that, as one historian put it, "the government possessed big answers to big problems" seemed to set the tone for the rest of the decade. However, that golden age never materialized. On the contrary, by the end of the 1960s, despite the 1969 "Summer of Love," it seemed that the nation was falling apart. Lyndon Johnson's "Great Society" splintered as the Democratic Party split and America became increasingly enmeshed in the Vietnam War.
