FDR and the Derms lied to the American people about FDR's health during the 44 election. It's not really sure is FDR was compos mentos during the Yalta meeting..he wasn't speaking to his wife at the time, so who knows who was really calling the shots..Stalin had a great many double agents inside the administration....We may never realize how lucky we are that some in the Dem party forced Wallace off the ticket.
Officially, on July 21, 1940, the governments of Lithuania, Latvia, and Estonia asked to be admitted to the U.S.S.R. I don't know the details but it certainly wasn't a free choice or the wish of the publics of those three countries--it was certainly coercion, whether Stalin had recently forced them to choose compliant leaders or whether the pre-existing leaders just submitted to overwhelming force. It was part of the spoils granted to Stalin by the Hitler-Stalin Pact of August 1939.
