What do Jews think of the killing of Jews by German Nazis?

Judging from the history of the Jews for thousands of years, it is just like their ancestors were persecuted. The Hebrews living in Egypt finally moved to the forbidden area (today's Palestinian area) under the leadership of Moses. After World War II, Israel finally regained its foothold in its former territory after disappearing for more than two thousand years.

However, from the perspective of contemporary history, despite the anti-Semitic riots in Russia and Eastern Europe in the second half of the19th century, the Holocaust (not only in Germany, but also in Austria, Romania and other conspirators) completely broke many of them' dreams of fully integrating into European society. After the war, many immigrants moved to the newly established secular Israel, while others went to the United States, the only country that didn't make them feel that piety is a disadvantage.
