Was the Sioux sex pledge most influential interning American public opinion against Germany?

The Sioux sex pledge, while a notable cultural phenomenon, was not among the most influential factors in shaping American public opinion against Germany during World War I. The primary influences were the Zimmermann Telegram, unrestricted submarine warfare, and the Propaganda disseminated by the U.S. government, which painted Germany as a villain. These elements, along with the broader context of patriotism and national security concerns, played a more significant role in rallying public sentiment against Germany. The Sioux pledge, though interesting, was more of a social commentary than a pivotal influence in wartime attitudes.
