Answer:
The difficult political and social climate that the United States was going through, both in external relations and in its internal organization, led to one of the most notable revolutions in the country and in the entire world. The conflict of <u>the Vietnam War</u> raised suspicions in many North American citizens, who, after the two world wars, were not clear about the purpose of another war that, they claimed, would only bring suffering. On the other hand, there were new protests by the African-American population in the country and led by Martin Luther King Jr. in t<u>he movement for civil rights for African-Americans.</u> All this was gradually consolidated after the shock caused in the American society by <u>the murders of John F. Kennedy and Martin Luther King</u>
Explanation:
This beginning of the decade is representative of a period that would be characterized by international confrontations and protests by an increasingly critical citizenry with the actions of its rulers and the situation that was taking shape in the world after the post-war economic recovery: protest movements against <u>the Vietnam war</u>; against the invasion of the Soviet troops in Czechoslovakia, in the Prague Spring; in May '68 against the established order, during the student and union revolts that began in France and spread rapidly to other countries. The sociocultural effects of these protest movements are still being felt today. It is also a decade in which a large number of political assassinations occur, an example of which is <u>the deaths of John F. Kennedy, Malcolm X, Martin Luther King and Robert F. Kennedy.</u>
