I asked this question on the old literature site, it got migrated to the science fiction and fantasy site, and then was later closed as off-topic. I figured that I might as well ask the question here.
I remember reading somewhere that Mr. Pilkington, Frederick, and the other farmers in Animal Farm symbolized different countries, but I forgot which country they each symbolized. Is that true, and if it is, can someone remind me which countries the individual farmers symbolized?
