A “Russian Khazar” mentioned in the article is Walt W. Rostow. He is a contemporary with other British Pilgrims, including Henry Stimson, Robert Patterson, William J. Donovan, Edward Landsdale and Henry Kissinger (Rockefeller’s man) — all organizers of the Marshall Plan fascization of world commerce as the planned outcome of the British Pilgrims false flag called WWII

“ Rostow” is Sir Walter Rostow, a “staunch anti-communist”; curiously, parents were socialists. It appears that he pushed communism on the U.S. State Department, South East Asia and China for British MI6 while the his propaganda said the opposite.
Rostow’s career was smothered in British Pilgrims Society control.
