They were kids at summer camp, passing hot days in routine activity and comradery. They were also learning to speak German, singing German songs, practicing military drills and greeting superiors with Hitler salutes. Wearing Nazi-style uniforms, the children marched, took rifle practice, and raised Hitler Youth banners. There were 16 locally organized camps like this one in the 1930s.

The campers’ parents belonged to the German American Bund, people of German ancestry who formed citizens groups in many countries extolling “German virtues” and lobbying for causes helpful to Nazi Party goals. The German American Bund formed in 1936 as “an organization of patriotic Americans of German stock,” according to Alan Taylor writing in The Atlantic in June, 2017. The U.S. Bund soon boasted tens of thousands of members across 70 regional divisions.

In 1939, the Bund held an “Americanization” rally in New York’s Madison Square Garden to denounce Jewish conspiracies, FDR and others. Attended by 20,000 supporters, the 27 photos of the rally, and the children’s camps, included in Taylor’s Atlantic piece, are chilling.

As WWII began the Bund was disbanded, its leader arrested for embezzlement and deported to Germany. But the American Bund happened. Right here in the U.S. we had a large, active, hate-filled Nazi group training its youth to be brown-shirts. It was our own Third Reich.

Arne Bernstein, author of Swastika Nation, learned about American Nazis first-hand as a young man when a neo-fascist group threatened his Jewish neighborhood. “In the 1930s, 1940s and beyond,” he wrote on The History Reader blog in 2013, “fascism and Nazi loyalty was as American as a proverbial apple pie.”

Bernstein says the German-American Bund eventually boasted a following of 200,000 nationwide. The FBI put the number at somewhere between 6,000 to 8,000 while an American Legion study found over 25,000 members. Whatever the actual number of American Nazis, there were enough of them to develop “a nationwide system of family retreats, businesses, publications” and Americanized versions of Hitler Youth and SS squadrons. Among those who didn’t seem to have a problem with the Bund were Henry Ford and Charles Lindbergh, along with the 15,000 members of The Silver Legion of America.

In 1935 Sinclair Lewis published a novel called It Can’t Happen Here. Like The Handmaid’s Tale, it’s making a comeback now. Lewis’s novel is a cautionary, alarming and seemingly prescient tale, about the fragility of democracy. It tells the story of an elected authoritarian president who becomes a dictator in the time of the Great Depression. The country’s new president wants to save America from welfare cheats, sex, crime, and a liberal press, as the jacket cover says. Sound familiar?

Upon publication, the book originally resonated for Americans worried about the possibility of a fascist regime in this country, and the growth of such regimes abroad – think Hitler, Mussolini, and now right-wing factions rising in Europe, again in times of political upheaval and economic turmoil.

Lewis wasn’t the only one writing about the threat of fascism as American angst grew. Articles proliferated, one by Walter Lippman, who noted that the country had “come to a period of discouragement,” as Michael Meyer noted in his introduction to the novel’s new edition. Myer points out that America had its fair share of right-wing polemicists then as now. William Randolph Hearst proclaimed, for example, that “whenever you hear a prominent American called a ‘Fascist,’ you can usually make up your mind that the man is simply a loyal citizen who stands for Americanism.”

By page two of Lewis’s novel, readers know what’s coming, foreshadowing a chilling sense of our own time, when a general rhapsodizes on the idea of nationalism. “Our highest ambition is to be let alone … We must be prepared to defend our shores against all the alien gangs of international racketeers that call themselves ‘governments.’ …A great nation must go on arming itself more and more…for peace….” And on goes the diatribe about isolationism, military strength, alien gangs and other perceived threats to thunderously affirming applause.

Lewis’s novel is full of fiery speeches, proselytizing pastors and politicians, simplistic rhetorical proclamations, and bizarre claims that grow more fervent as the noose tightens on a nation. While the story moves all the way to executions and concentration camps – scenarios we are not ready to imagine possible – it is still a cautionary tale, one that ends with the liberal journalist and leader of the resistance fleeing to Canada “where quiet men awaited news of freedom.”

The leader has realized too late that “the tyranny of this dictatorship isn’t primarily the fault of Big Business, nor of the demagogues who do their dirty work. It’s the fault of … all the conscientious, respectable, lazy-minded [liberals] who have let the demagogues wriggle in, without fierce enough protest.”

That’s an analysis worthy of our attention, as Lewis’s novel is a book worth reading in these troubling times. Because it really can happen here. It already has.

Right after the election of Donald Trump, I was anxious in a cerebral way. I experienced a level of anxiety, disbelief and grave concern that can be energizing and I jumped into the resistance movement full steam ahead, full of adrenalin produced by stress.

Now I find myself in a state of deep, visceral anxiety. I am truly afraid – of lots of things. Anti-Semitism and white supremacists. A Muslim ban and immigration policy that have barely begun to reveal their terrible consequences. The threat of being too late to save the planet from the effects of climate change and global warming. The threat of nuclear war. The idea of millions of people dying for lack of health care. The demise of public education and necessary regulation. The disasters waiting to happen if we don’t fix our failing roads, rails, bridges, tunnels and airports.

But even worse than that, I’m afraid because I can see truth dying in this country and because I think the freedoms we take for granted will be next. I’m afraid because conspiracy theories designed to destroy our trust in the institutions that have existed to keep us “free and the brave” are giving way to an alternative reality. I’m afraid because we are rapidly descending into a state of nationalism in which a few madmen will kill our system of checks and balances, ignore our justice system, attempt mind control by denying media legitimacy as they spew lies that people begin to believe because they are repeated so often.

Think that’s going too far? Why, then, have agencies been rapidly dismantled, their senior staff fired, so that no institutional memory or proven expertise prevails? Why have government agencies been silenced? Why has critical information been removed from agency websites? Why are Alt-Right media being credentialed while mainstream reporters are denigrated and denied access? Why are so many clearly corrupt, unqualified people now in charge?

When all these egregious, undemocratic actions began occurring, we cautioned against “normalizing” what was happening. Now we are beginning to hear a new word: “Destabilization.” That’s a serious word, one that we can no longer ignore or make nervous jokes about. Our collective fear is not subliminal now; it has grown into overt, overwhelming anxiety because we are staring at the real possibility of witnessing the demise of democracy in the face of rising fascism.

The idea that our future is in the hands of a few deranged demagogues is nothing short of terrifying. Our president is not the leader of the free world; he is the emperor with no clothes and he is madly marching toward the abyss, dragging us behind him.

So, my question is: Why are we so powerless to stop him and his cronies? How do we move beyond hand-wringing and bearing witness before it’s too late? (And there comes a time when it is too late.) We are, of course, up against a Congress largely devoid of compassion and intellect, but we must bring enough pressure to bear on our legislators that we deny the encroaching evil. It falls to us, concerned constituents, to ensure such evil does not prevail. It falls to us to see that America does not die for lack of goodness.

As Rabbi Hillel once asked, “If not now, when? If not me, who?”

Every day social media and mainstream news reveal more Russian collusion, more heinous decisions emanating from the West Wing asylum, more lies, more Draconian travesties from Donald Trump’s henchmen. They simply cannot be allowed to continue.

Nor can the Mar a Lago madman in the attic. We cannot think that reason will ultimately rid us of his scourge . Reason alone will not stem the tidal wave of his hate or rid us of his putrid swamp, full of predators snapping at our feet.

We have heard already the language of “purges” and women as “hosts,” both terms reeking of 1984 and The Handmaid’s Tale. We’ve seen good people, like TSA agents, airline personnel and border patrol, do bad things. We’ve seen bad people do bad things, like deface synagogues, burn down mosques, march in favor of killing people or forcing them to abandon the country of their birth.

We can’t wait for a dramatic disaster to understand that the time has come to reclaim our country and to take back its values. We can’t allow ourselves to be sucked into the irreversible vortex of Bannon’s nationalism or Putin’s agenda or Trump’s narcissism.

And so I ask again, as Rabbi Hillel did: If not now, when? If not us, who? And if not now, and not us, will we be forced, sooner than we think, to ask how it happened?
