I'd like to note that I was incorrect when I said above that the Soviet Union attacked Estonia, Latvia, and Lithuania. According to page 15 of "A Frozen Hell: The Russo-Finnish War of 1939-40", Stalin absorbed Estonia by inviting the foreign minister of Estonia to Moscow on September 22, and one week later an agreement was signed that gave Moscow the right to station troops, aircraft, and naval units in that country. In effect, Estonia became part of the Soviet Union.JAR said:After strengthening its position in Poland, the Soviet Union attacked Estonia, Finland, Latvia, and Lithuania. I got this information from page 504-505 of the sections titled "Soviet Foreign Policy Between Wars" and "Territorial Expansion" of the section titled "History" of the article titled "Russia" from the "Q-R" volume of "The World Book Encyclopedia" copyrighted in 1962.
Then the foreign ministers of Latvia and Lithuania were invited to Moscow during the first week of October, and on the fifth and eleventh of that month, they also signed "mutual assistance" treaties with the USSR that would lead to them becoming part of the Soviet Union.
There was no attack by Soviet Union against Estonia, Latvia, and Lithuania. I mistakenly thought there was because in the World Book Encyclopedia article I originally got the information from, it said, "After strengthening its position in Poland, the Soviet Union turned on Estonia, Finland, Latvia, and Lithuania."
I misinterpreted "turned on" as meaning "attacked." It didn't occur to me that something else could be meant by "turned on."
