On February 20, 1939, a crowd of 20,000 gathered at Madison Square Garden for a “Pro-American” rally sponsored by the German American Bund, a pro-Nazi organization. I’d seen photos of the event, but I didn’t know there was film footage as well.

There is a moment during an on-stage scuffle involving a protestor (a Brooklyn man named Isadore Greenbaum), right around the 4:15 mark, when a young boy in the background rubs his hands and does a gleeful jig — I…I don’t even know what to say about how I felt watching that. After Greenbaum is spirited away, his clothes nearly ripped from his body, the crowd roars. As director Marshall Curry said in an interview about the film:

In the end, America pulled away from the cliff, but this rally is a reminder that things didn’t have to work out that way. If Roosevelt weren’t President, if Japan hadn’t attacked, is it possible we would have skated through without joining the war? And if Nazis hadn’t killed American soldiers, is it possible that their philosophy wouldn’t have become so taboo here?
