It came to America with the first Jews, in the 17th Century.
There were pogroms in Russia until very recently.
Judaism is a religion. Jews can live in, or come from, just about any country. Today, the largest Jewish communities are in America and Israel, with smaller numbers of Jews in almost every country in the world.
There are poor Jews in America in 2011. Jews are like everyone else in that regard.
No. America fought in WW2, one result of WW2 was to free those Jews who had not already been killed, but the USA did not fight in a war to free Jews.
If you are referring to the liberation after the Holocaust, then no. Jews went all over the world, but especially to:IsraelNorth AmericaAustraliaArgentinathe UK
Israel and America.
America not 'save the Jews from Hitler's attack'. The Holocaust was not some sentimental B-movie with a happy ending.
No, Jews do not come from Mars. Jews are a religious and ethnic group with roots in ancient Israel and diaspora communities around the world, but their origins are not extraterrestrial.
Sadly America did very little as a nation or a government to save the Jews of Europe. American immigration policy allowed very few European Jews to come to the USA even after the intentions of Hitler were known. The allies refused repeated requests by leading Jews to bomb the railroads to the Concentration Camps. In Israel today there is a museum named Yad Vashem. It is the Israeli national memorial to those who died in the Holocaust and a museum. Yad vashem has honored 23,000 non-Jews for saving Jewish lives during World War Two. It is very telling that while several thousand of those honored are from Poland only 4 come from America and only 14 from England. America basically abandoned the Jews to their fate.
Jews live around the world, but primarily in Israel and America.
Judaism goes wherever the Jews go. There are Jews in every country, but especially (in descending order) in Israel, America, Europe, and South America.
