Separated from National Socialism by time and luck, we find it easy to dismiss Nazi ideas without contemplating how they functioned. Our forgetfulnes… - Timothy Snyder

Because the American federal government uses mercenaries in warfare and American state governments pay corporations to run prisons, the use of violence in the United States is already highly privatized. What is novel is a president who wishes to maintain, while in office, a personal security force which during his campaign used force against dissenters. As a candidate, the president ordered a private security detail to clear opponents from rallies, but also encouraged the audience itself to remove people who expressed different opinions. A protestor would first be greeted with boos, then with frenetic cries of “USA,” and then be forced to leave the rally. At one campaign rally the candidate said, “There’s a remnant left over. Maybe get the remnant out. Get the remnant out.” The crowd, taking its cue, then tried to root out other people who might be dissenters, all the while crying “USA.” The candidate interjected: “Isn’t this more fun than a regular boring rally? To me, it’s fun.” This kind of mob violence was meant to transform the political atmosphere, and it did.

[A] turning point of the twentieth century: the Nazi-Soviet alliance... In September 1939, Nazi Germany and the Soviet Union both invaded Poland... In April 1940, the Soviet secret police murdered 21,892 Polish prisoners of war... shot in the back of the head at five killing sites, one of them the Katyn Forest... Only after the dissolution of the Soviet Union in 1991 could historians clarify... the mass murder had been deliberate policy, personally approved by Joseph Stalin. ...On February 3, 2010... the Russian prime minister made a surprising proposal: a joint commemoration... on the seventieth anniversary of the crime. On the seventh of April a Polish government delegation... arrived in Russia.
Two days after that, a second Polish delegation set out... One of its members was my friend Tomek Merta... April 10... Tomek boarded an airplane. It crashed... short of a landing strip at the Russian military airfield at Smolensk. There were no survivors.

Americans today are no wiser than the Europeans who saw democracy yield to fascism, Nazism, or communism in the twentieth century.
