By the end of their first year in office, Nixon and Kis-singer had conc-luded that the most effect-ive way to tip the military bal-ance in America's favor was to <em>destroy mili-tary </em><em>bases </em><em>in Cam-bodia</em>.
Kis-singer served as Nation-al Security Advisor and Secre-tary of State under Presi-dent Richard Nixon, and continued as Secre-tary of State under Nixon's succe-ssor Gerald Ford. With the death of Geo-rge Shultz in Feb-ruary 2021, Kis s-inger is the last surv-iving member of the Nixon administ-ration Cabinet.
Nixon and Kis-singer were both comm-itted to a real-ism that focused on American eco-nomic advant-ages and jettisoned moral-ism in foreign policy, seeking détente with Comm-unism and confront-ation with old allies who now had beco-me economic advers-aries.

freedom were treated with prejudice and had no right to vote etc. Making the
slogan just a slogan and not achieving the targeted goals.</span></span>
