The Containment Strategy was the principal strategy adopted by the US in foreign policy matters during the Cold War era.
It aimed to stop the expansion of the national enemy: communism, and in turn, of the URSS and the countries under its influence, that were denominated the Eastern Bloc. It consisted on responding to any attempt of expansion performed by the URSS, seeking to spread communism in Eastern Europe, Korea, China Africa, Vietnam, and Latin America.
Human autonomy is the key concept of Enlightenment ideas. This passage relates to those ideas because Napoleon is refering to the importance of reason over beliefs. When he says "the souls of men proceed along different roads" he is also claiming that any religion is valid to feel close to the creator. In a sense Napoleon makes reference to secularization (the idea of religion and politics should be separated and that one's method of worship should be a private matter). That is why he claims that he could be Catholic, Muslim, or Jew.
