Only the actuality of Hashem providing His own personal and heavenly nourishment, can answer that question. We too are recipients of Hashem's loving kindness. Unfortunately, these wanderings also have taken their toll on our people. Josepheus, the Jewish historian, who lived during the Roman occupation of the Holy Land, records that at the time of the destruction of our Temple, in the year 70 C.E., there were seven million Jews in the world, stretching from England in the north and reaching India in the east. If we presume for arguments sake, that half of the Jews in every generation were killed in pogroms, inquisitions and holocausts, which is not at all true, then today there should be in excess of fifty million Jews.
Assimilation is the only answer that makes sense.
More evil than Hitler, more devious than Chmeilnitsky and more offensive than forced conversions, is assimilation. We have falsely comforted ourselves in the ways of the world. Among us, there were always Jews who thought that the Jewish way was an anachronism - a lifestyle that is out of date and in need of modification. We had affairs with Buddhism, Hinduism and even Shintoism. We invented socialism, communism, even humanism.
