How did the actions taken by the federal government during times of war lead to the value of the Declaration of Independence?

During times of war, the federal government has often invoked the principles of the Declaration of Independence to rally support and unify the nation, emphasizing themes of liberty, self-determination, and justice. Actions such as conscription, resource allocation, and civil liberties restrictions have been justified by framing them as necessary to protect the values enshrined in the Declaration. This reassertion of the Declaration's ideals reinforces its significance as a foundational document, reminding citizens of their rights and the government's responsibility to uphold them. Thus, the Declaration's value is amplified as a symbol of American identity and purpose in the face of conflict.
