How many Jews did Hitler kill during World War II? How many more Jews fled to the United States?

40% of the Jews, approximately 6 million people.

At the end of the 19th century, due to intensified persecution in Eastern Europe, thousands of Jews fled here, most of them to the United States, Canada and Western Europe.

***About two million Jews immigrated to the United States, because at that time American society's attitude towards the Jewish community was relatively more tolerant than that of Eastern Europe.

The persecution of Jews in Europe reached its peak during World War II, when about 6 million Jews were exterminated in the Holocaust, which almost completely destroyed the 2,000-year cultural and historical accumulation of Jews in Europe.
