Step-by-step explanation:
The Committee on Public Information portrayed people who were against the war as unpatriotic in order to generate support for the war effort and to maintain national unity.
Through the use of propaganda, the committee aimed to create a sense of patriotism and loyalty among Americans by depicting those who opposed the war as disloyal or even traitorous.
By associating opposition to the war with being unpatriotic, the committee effectively silenced dissent and ensured that the majority of Americans remained supportive of the war.
