Explanation:
The NAACP’s legal strategy against segregated education culminated in the 1954 Supreme Court’s landmark Brown v. Board of Education decision. African Americans gained the formal, if not the practical, right to study alongside their white peers in primary and secondary schools. The decision fueled an intransigent, violent resistance during which Southern states used a variety of tactics to evade the law.
In the summer of 1955, a surge of anti-black violence included the kidnapping and brutal murder of fourteen-year-old Emmett Till, a crime that provoked widespread and assertive protests from black and white Americans. By December 1955, the Montgomery, Alabama, bus boycott led by Martin Luther King, Jr., began a protracted campaign of nonviolent civil disobedience to protest segregation that attracted national and international attention.
During 1956, a group of Southern senators and congressmen signed the “Southern Manifesto,” vowing resistance to racial integration by all “lawful means.” Resistance heightened in 1957–1958 during the crisis over integration at Little Rock’s Central High School. At the same time, the Leadership Conference on Civil Rights led a successful drive for passage of the Civil Rights Act of 1957 and continued to press for even stronger legislation. NAACP Youth Council chapters staged sit-ins at whites-only lunch counters, sparking a movement against segregation in public accommodations throughout the South in 1960. Nonviolent direct action increased during the presidency of John F. Kennedy, beginning with the 1961 Freedom Rides.
I think that the best answer is the geographic location: many other countries (Sweden for example) have tried being neutral at different times but did not manage to: but the fact that the US has only two boundaries, and that both other countries also have a history of fighting from independence from a European power, makes it possible that unless US decideds to get involved in international politics, it can be "left alone".
struggles for power between the president and the Congress-
Congress passed the Tenure of Office Act in order to limit
the President's powers and prevent President Andrew Johnson from discharging
radical Republicans from office. This resulted from a conflict between
President Andrew Johnson and the radical Republicans over the Reconstruction of
the South
