A bit of added detail:
I'd like to explain more about one item in the list above -- the policy of "brinkmanship" during the Eisenhower administration.
John Foster Dulles was Secretary of State under US President Dwight Eisenhower. Dulles held the office from 1953 to 1959. He wanted a change from what had been the "containment policy" which the US had followed during the Truman Administration, as recommended then by American diplomat George F. Kennan. Dulles felt the containment approach put the United States in a weak position, because it only was reactive, trying to contain communist aggression when it occurred.
Dulles sought to push America's policy in a more active direction; some have labeled his approach "brinkmanship." In an article in <em>LIFE </em>magazine in 1956, Dulles said, "The ability to get to the verge without getting into the war is the necessary art." He wasn't afraid to threaten massive retaliation against communist enemy countries as a way of intimidating them.
The goal of the writers of the Lecompton Constitution is humanitarian aid to slaves. It was proposed for the state of Kansas in response to the anti-slavery position of the 1855 Topeka constitution and other free state advocates. The constitution protected the slave holder rights, enshrined slavery and allowed voters the choice of allowing more slaves to enter the territory.
