Chosen people from the Caucasus

In Chosen People From the Caucasus, Bradley extends his iceman theory to a provocative and controversial discussion of the Hebrews. "Given their relatively small numbers, Jews have had an inordinately great influence on Western Civilization," says Bradley. "And given the fact that Western civilization has come to dominate the world over the past five hundred years, Jews have accordingly played a major role in the unfolding drama of all humanity." Is this historical phenomenon merely coincidence, Jewish birthright or are there more plausible explanations?
