Writing in The Arizona Journal of International & Comparative Law Stephen Halbrook demonstrates that German Jews and other German opponents of Hitler were not destined to be helpless and passive victims. (A magazine article by Halbrook offers a shorter version of the story, along with numerous photographs. Halbrook's Arizona article is also available as a chapter in the book Death by Gun Control, published by Jews for the Preservation of Firearms Ownership.) Halbrook details how, upon assuming power, the Nazis relentlessly and ruthlessly disarmed their German opponents. The Nazis feared the Jews — many of whom were front-line veterans of World War One — so much that Jews were even disarmed of knives and old sabers.
The Nazis did not create any new firearms laws until 1938. Before then, they were able to use the Weimar Republic's gun controls to ensure that there would be no internal resistance to the Hitler regime.
The Nazi disarmament campaign began as soon as Hitler assumed power in 1933. While some genocidal governments (such as the Khmer Rouge in Cambodia) dispensed with lawmaking, the Nazi government followed the German predilection for the creation of large volumes of written rules and regulations. Yet it was not until March 1938 (the same month that Hitler annexed Austria in the Anschluss) that the Nazis created their own Weapons Law. The new law formalized what had been the policy imposed by Hitler using the Weimar Law: Jews were prohibited from any involvement in any firearm business.
Despite having an extremely powerful army, the Nazis still feared the civilian possession of firearms by hostile civilians. Events in 1943 proved that the fear was not mere paranoia. As knowledge of the death camps leaked out, determined Jews rose up in arms in Tuchin, Warsaw, Bialystok, Vilna, and elsewhere. Jews also joined partisan armies in Eastern Europe in large numbers, and amazingly, even organized escapes and revolts in the killing centers of Treblinka and Auschwitz. There are many books which recount these heroic stories of resistance. Yuri Suhl's They Fought Back (1967) is a good summary showing that hundreds of thousands of Jews did fight. The book Escape from Sobibor and the eponymous movie (1987) tell the amazing story how Russian Jewish prisoners of war organized a revolt that permanently destroyed one of the main death camps.
No one can foresee with certainty which countries will succumb to genocidal dictatorship. Germany under the Weimar Republic was a democracy in a nation with a very long history of much greater tolerance for Jews than existed in France, England, or Russia, or almost anywhere else. Zimbabwe's current gun laws were created when the nation was the British colony of Rhodesia, and the authors of those laws did not know that the laws would one day be enforced by an African Hitler bent on mass extermination.
One never knows if one will need a fire extinguisher. Many people go their whole lives without needing to use a fire extinguisher, and most people never need firearms to resist genocide. But if you don't prepare to have a life-saving tool on hand during an unexpected emergency, then you and your family may not survive.
In the book Children of the Flames, Auschwitz survivor Menashe Lorinczi recounts what happened when the Soviet army liberated the camp: the Russians disarmed the SS guards. Then, two emaciated Jewish inmates, now armed with guns taken from the SS, systematically exacted their revenge on a large formation of SS men. The disarmed SS passively accepted their fate. After Lorinczi moved to Israel, he was often asked by other Israelis why the Jews had not fought back against the Germans. He replied that many Jews did fight. He then recalled the sudden change in the behavior of the Jews and the Germans at Auschwitz, once the Russian army's new "gun control" policy changed who had the guns there: "And today, when I am asked that question, I tell people it doesn't matter whether you're Hungarian, Polish, Jewish, or German: If you don't have a gun, you have nothing."
