Jones: (from your link) https://en.wikipedia.org/wiki/Gareth_Jones_(journalist)#Life...
"In 1931 he was offered employment in New York City by Dr Ivy Lee, public relations advisor to organisations such as the Rockefeller Institute, the Chrysler Foundation, and Standard Oil, to research a book about the Soviet Union. In the summer of 1931 he toured the Soviet Union with H. J. Heinz II of the food company dynasty, producing a diary published by Heinz as Experiences in Russia 1931, a diary which probably contains the first usage of the word "starve" in relation to the collectivisation of Soviet agriculture. In 1932 Jones returned to work for Lloyd George and helped the wartime Prime Minister write his War Memoirs.
During the 1930s, he was a reporter for the Western Mail.[2] In late January and early February 1933 Jones was in Germany covering the accession to power of the Nazi Party, and was in Leipzig on the day Adolf Hitler was appointed Chancellor. A few days later on February 23 in the Richthofen, the fastest and most powerful three-motored aeroplane in Germany, he became the first foreign journalist to fly with Hitler as Jones accompanied Hitler and Joseph Goebbels to Frankfurt where Jones reported for the Western Mail on the new Chancellor's tumultuous acclamation in that city."
It's called the Cold War. Liars lied about liars. All of your sources are committed anti-communists willing to do whatever it took to bring down the USSR. Do you really think they wouldn't lie about this stuff?
