Final answer:
President Franklin Roosevelt's "Four Freedoms" speech supported the end of oppression and start of universal liberty by presenting a vision of four fundamental freedoms: speech, worship, want, and fear, which are aligned with the ideals of the United Nations and the Atlantic Charter.
Step-by-step explanation:
In his "Four Freedoms" speech, President Franklin Roosevelt calls for the end of human oppression and the beginning of universal liberty. One sentence from the speech that best supports this analysis is when Roosevelt talks about the "four essential human freedoms" that the future world should be founded upon, underlying the need for freedom of speech, freedom of worship, freedom from want, and freedom from fear. This reflects his vision for a post-war world where every individual could experience these fundamental rights as a part of their everyday lives.
Moreover, the speech mentions the universal declaration of human rights and Roosevelt's support for the United Nations charter ideals, which enshrine these freedoms. The Atlantic Charter, a pivotal document signed by Roosevelt and Churchill, also reinforces these ideals and emphasizes economic and political cooperation among nations, further supporting the analysis of Roosevelt's advocacy for ending oppression and promoting liberty.
