Nobody who has lived through the rise of the violent anti-Semitism which led to Hitler can refuse Mrs. Thatcher admiration for her courageous and outspoken warning. When I grew up in Vienna the established Jewish families were a generally respected group and all decent people would frown upon the occasional anti-Jewish outbursts of a few popular politicians. It was the sudden influx of large numbers of Galician and Polish Jews [during World War I] … which in a short period changed the attitude. They were too visibly different to be readily absorbed.
