When two Swedish Nazis thought their group’s leaders had gone soft, they went to train with Russian paramilitaries, before returning home to carry out an attack. Their case shows how nationalist extremism across Europe is being transformed by the conflict in Ukraine.

As director Christopher Nolan’s war epic Dunkirk premiered last Thursday, Russia’s Embassy in the U.K. shared its thoughts on Britain and France’s contribution to the war effort over Twitter. Things escalated quickly. “Dunkirk was caused by the appeasement, opposed by (Winston) Churchill,” the embassy tweeted, referring to the British wartime prime minister. The “phony war was its last stage,” it added, referring to the first months following Britain and France’s declaration of war, where they failed to launch any major offensive to rescue their ally Poland from the German advance.

If white supremacists can equate “Muslims” with attacks on LGBTQ people—and women—they might be able to attract liberals and moderates into a kind of anti-immigrant “big tent.” This would complement their effort to portray racism as “pro-worker.” By Donna Minkowitz.

Yad Vashem extended the invitation after the White House's Press Secretary drew an especially controversial comparison between Syria's Assad and Nazi leader Hitler. Spicer triggered an uproar on Tuesday (April 11) by saying Adolf Hitler did not use chemical weapons. He apologized after his comments drew immediate criticism on social media and elsewhere for overlooking the fact that millions of Jews were killed in Nazi gas chambers. As Spicer told CNN: "It was a mistake. I shouldn't have done it and I won't do it again." A senior member of Israel's government welcomed Spicer's apology on Wednesday.

Born to the director of the Berlin Zoo, Lutz Heck seemed destined for the world of wildlife. But instead of simply protecting animals, Heck had a darker relationship with them: he hunted and experimented with them. In the new movie The Zookeeper’s Wife (based on a nonfiction book of the same title by Diane Ackerman), Heck is the nemesis of Warsaw zookeepers Antonina and Jan Zabinski, who risk their lives to hide Jews in cages that once held animals. All told, the couple smuggled around 300 Jewish people through their zoo.

My grandparents were Nazis. It took me until recently to be able to say — or write — this. I used to think of and refer to them as “ordinary Germans,” as if that was a distinct and morally neutral category. But like many “ordinary Germans,” they were members of the Nazi Party — they joined in 1937, before it was mandatory. My grandmother, who lived to be almost 100, was not, as I knew her, xenophobic or anti-Semitic; she did not seem temperamentally suited to hate. Understanding why and how this woman I knew and loved was swept up in a movement that became synonymous with evil has been, for me, a lifelong question.
