Orwell wrote the book between November 1943 and February 1944, when the United Kingdom was in its wartime alliance with the Soviet Union against Nazi Germany and the British intelligentsia held Stalin in high esteem, which Orwell hated.
So George, any other particular grievances you may have with any other groups during 1943-1944? Is there any other country getting on your nerves, causing you to hate it? Just any global power that may be doing things that would cause you, an author, to spend a year writing about it?
