What was a reason many Americans were suspicious of German immigrants during WW1?

During World War I, many Americans harbored suspicions of German immigrants primarily because they were considered potential spies for Germany. This suspicion was fueled by the wartime context, where national allegiance was scrutinized, and the fear of espionage was prevalent. The U.S. was engaged in a conflict against Germany, and as a result, any individuals perceived as having connections to or sympathies for the enemy were viewed with distrust. This led to a wave of xenophobia, resulting in German Americans facing discrimination, violence, and a loss of rights during the war period.

While speaking a different language or being wealthy could contribute to feelings of mistrust, they were not specific reasons for suspicion in the same way that the espionage narrative was. Additionally, while some individuals did support pacifism, this was not the primary concern that led to widespread animosity towards German immigrants during the war; rather, the overarching fear of betrayal and loyalty to the enemy was the driving factor behind the suspicions.
