Patrick Cleburne writes at vdare on Cold War spying, describing and interview between Peter Brimelow and Diana West: https://vdare.com/articles/wondering-why-u-s-immigration-policy-is-run-by-communists-listen-to-diana-west-and-peter-brimelow
As he notes, the great majority of spies for the USSR were Jews—part of the pro-communist Jewish left that was very mainstream in the Jewish community. Cleburne’s vdare article references an article by John Graham in TOO which contains the following:
What younger observers will be able to recognize, however, is the familiar pattern of fanatical denial of truth and willful ignoring of reality still occurring in MSM discussions of these matters, for instance in the New York Times obituary for Coplon: Judith Coplon, Haunted by Espionage Case, Dies at 89 by Sam Roberts (March 1, 2011).
Judith Socolov, who as a diminutive Barnard graduate named Judith Coplon was convicted of espionage more than 60 years ago after embracing a utopian vision of communism and falling in love with a Soviet agent, died Saturday in Manhattan.
Coplon was convicted of course not for utopianism or falling in love, but for betraying her (putative) country at the time of its greatest peril – Germany and Japan never threatened America the way the Soviet Union did. …
It stems of course from the fact that the overwhelming majority of the important spies for Russia were Jews. Coplon, the Rosenbergs, Harry Dexter White, Theodore Hall , Maurice Halperin – the list goes on and on. There were a few leftist WASPS – Alger Hiss, Lauchlin Currie, Elizabeth Bentley – but they were distinctly a minority.
