Why does Chicago have a monument named for fascist leader Italo Balbo?

There’s an ancient Roman column in Chicago hidden in plain sight near Soldier Field. It was a gift given by Italian Fascist dictator Benito Mussolini during the 1933-1934 Chicago World’s Fair, commemorating a daring transatlantic flight to the fair by Italian Air Marshal Italo Balbo. In a time when controversial monuments get removed, why does this one still stand?
