Final answer:
The concept of 'freedom from fear' has shifted from Roosevelt's focus on peace and security during wartime and economic struggles to Obama's focus on global cooperation against terrorism and economic uncertainties. Both presidents emphasized the goal of a secure society, but the nature of the threats they addressed differed according to their historical contexts.
Step-by-step explanation:
The idea of "freedom from fear" has evolved between the eras of President Franklin Delano Roosevelt's "Four Freedoms" speech and President Barack Obama's "Welcoming Remarks" speech.
Looking at Roosevelt's Four Freedoms, which include freedom of speech, freedom of worship, freedom from want, and freedom from fear, this concept was presented as a cornerstone of peace and security in a world threatened by war and economic struggle.
In Roosevelt's time, freedom from fear largely referred to protection from the ravages of war and totalitarian regimes, while in Obama's era, it expanded to include safeguarding against terrorism and promoting a shared sense of resilience and community.
This shift highlights how historical context shapes presidential rhetoric and national priorities. The differences are marked by evolving global threats, while the similarity lies in the enduring aspiration for a secure and peaceful society.
Using the "Wedding Cake" model which prioritizes and organizes ideas, the first layer would address the general concept of freedom from fear, followed by the specific nuances each President has attached to this freedom.
