3. If Americans take sides in the war, Wilson is concerned that... O the US will become involved in the fighting
society will become deeply divided
loyalty will lead to partisanship

Explanation:

Recent research by political scientists at Vanderbilt University and other institutions has found both Republicans and Democrats distressingly willing to dehumanize members of the opposite party. “Partisans are willing to explicitly state that members of the opposing party are like animals, that they lack essential human traits,” the researchers found. The president encourages and exploits such fears. This is a dangerous line to cross. As the researchers write, “Dehumanization may loosen the moral restraints that would normally prevent us from harming another human being.”

Outright political violence remains considerably rarer than in other periods of partisan divide, including the late 1960s. But overheated rhetoric has helped radicalize some individuals. Cesar Sayoc, who was arrested for targeting multiple prominent Democrats with pipe bombs, was an avid Fox News watcher; in court filings, his lawyers said he took inspiration from Trump’s white-supremacist rhetoric.
