I personally know of many immigrants from Eastern Europe who claimed to be Jewish as a means of claiming persecution and obtaining citizenship in America.
Could Mike Wallace's family have done the same? His disparaging remarks towards hispanics and blacks shows a lack of empathy that runs counter to his own narrative.
Maybe his family were plants from the 1917 revolution who were tasked with a decades long mission to infiltrate American media so that the faux pas that happened in 1919 or so with Henry Cabot Lodge would not be repeated? Quick note Henry Cabot Lodge was the senator who scuttled (((their))) plans for a one world government via the League of Nations post WWI.
