The front-page headline of the Brattleboro Daily Reformer on March 29, 1933, read, "Jewish Boycott Taking Effect: Jewish Shops in Berlin Picketed by Storm Troopers." The Rutland Herald proclaimed on November 11, 1938, "Terror Reigns as Angry Nazis Wreak Vengeance on Jews." Below it, an ominous prediction: "More Trouble Ahead." By November 25, 1942, the Burlington Free Press and Times was reporting that approximately half of the estimated 4 million Jews in Nazi-occupied Europe had been killed in a German-led "extermination campaign." And yet, when a public opinion poll conducted in January 1943 asked Americans whether such reports were true or just rumors, only 48 percent believed they were real. America's seeming indifference to the genocide of Jews in the 1930s and '40s has often been summed up in four words: Americans did not know. But a traveling exhibit, on display at the Stowe Free Library until December 16, challenges that long-held assumption. "Americans and the Holocaust" is a compelling new exhibition created by the United States Holocaust Memorial Museum in Washington, D.C., in partnership with the American Library Association. The show poses two fundamental questions about Nazi Germany's persecution of European Jews and other groups: What did Americans know about the Holocaust, and when did they know it? And what more could have been done to prevent the genocide? While the exhibition does a good job of answering the first question, it leaves the second for viewers to ponder themselves. For a small show, "Americans and the Holocaust" packs a punch, focusing solely on public sentiments and behaviors on this side of the Atlantic. As visitors enter the exhibition, a touch screen displays a map of the U.S. that allows viewers to click on any state and read the dispatches from Europe that were published in local newspapers like those in Brattleboro, Rutland and Burlington. Evident from the journalism and public opinion polls is that many Americans at the time subscribed to an isolationist worldview, especially as it related to the war in Europe. This attitude held true even when the consequences of U.S. nonintervention were glaringly obvious. Consider one poll from November 1938 that asked, "Do you approve or disapprove of the treatment of Jews in Nazi Germany?" While 94 percent of Americans expressed disapproval, a follow-up question asked: "Should we allow a larger number of Jewish exiles from Germany to come to the United States…
