The US hoped to stay out, not taking part in WW2. Between 1935 and 1939 the US Congress passed a series of Neutrality Acts meant to prevent Americans becoming involved. President Harry S. Truman was quoted as saying by the New York Times in June 24, 1941 : “If we see that Germany is winning, we ought to help Russia and if Russia is winning we ought to help Germany, and that way let them kill as many as possible, although I don’t want to see Hitler victorious under any circumstances. Neither of them thinks anything of their pledged word.”
