Analysis of information sources in references of the Wikipedia article "Tỉnh tự trị Nagorno-Karabakh" in Vietnamese language version.
Of all the documents I have seen, there is no direct evidence of Stalin doing or saying something in those 12 days in the summer of 1921 that [resulted in this decision on Karabakh]. A lot of people just assume that since Stalin was an evil person, it would be typical of someone evil to take a decision like that.
