Not sure what's going on here, but let's add some perspective:
It was rewarded to Stalin not so much because Indians are communists, but because Stalin scored a major victory against the Nazis. The headress and honorary title were bestowed for Stalin's military achievement, not really because they agreed with communism.
Americans, in 1941, had a favorable view of Stalin. Again, not because Americans thought that much of communism, but that he was putting up a fight against Hitler. What also happened was that foreign journalists, including Americans, when reporting on the Soviets knew the truth of Stalin and the failure of communism...but chose to write glowing stories otherwise because they could be thrown out of Russia, arrested and jailed...or disappeared. So, US citizens were tricked into a favorable opinion of Stalin. In 1941, the Socialists in the US still had political power as it was not quite seen as it is today. My point is that everyone was fooled; not just the Indians.
The group that awarded Stalin honorary chief status and the headress was the Indian Confederation of America...which represented only 27 tribes between North and Central America. The US itself had close to 570 tribes in 1941, so this really wasn't representative of ALL Indian tribes and nations.
