Defend institutions. It is institutions that help us to preserve decency. They need our help as well. Do not speak of “our institutions” unless you make them yours by acting on their behalf. Institutions do not protect themselves. They fall one after the other unless each is defended from the beginning. So choose an institution you care about — a court, a newspaper, a law, a labor union — and take its side.

A nationalist will say that “it can’t happen here,” which is the first step toward disaster. A patriot says that it could happen here, but that we will stop it.

Now we will live!” This is what the hungry little boy liked to say, as he toddled along the quiet roadside, or through the empty fields. But the food that he saw was only in his imagination. The wheat had all been taken away, in a heartless campaign of requisitions that began Europe’s era of mass killing. It was 1933, and Joseph Stalin was deliberately starving Soviet Ukraine. The little boy died, as did more than three million other people. “I will meet her,” said a young Soviet man of his wife, “under the ground.” He was right; he was shot after she was, and they were buried among the seven hundred thousand victims of Stalin’s Great Terror of 1937 and 1938. “They asked for my wedding ring, which I….” The Polish officer broke off his diary just before he was executed by the Soviet secret police in 1940. He was one of about two hundred thousand Polish citizens shot by the Soviets or the Germans at the beginning of the Second World War, while Nazi Germany and the Soviet Union jointly occupied his country. Late in 1941, an eleven-year-old Russian girl in Leningrad finished her own humble diary: “Only Tania is left.” Adolf Hitler had betrayed Stalin, her city was under siege by the Germans, and her family were among the four million Soviet citizens the Germans starved to death. The following summer, a twelve-year-old Jewish girl in Belarus wrote a last letter to her father: “I am saying good-bye to you before I die. I am so afraid of this death because they throw small children into the mass graves alive.” She was among the more than five million Jews gassed or shot by the Germans.
