They had a choice, they were the once who chose it. Again, they started the holocaust before the Germans came. 
Who cares what they decided in 1950. It was already the cold war offcourse they will try to suck-up to ex-Nazis to tear the Soviet Union from the inside. They were involved in the holocaust, it's a fact, ask any Estonian Jew. Jews always were in every independence movement so somwhere they would be excepted. I saw a ducumentary with Jews from Estonia who menneged to escape with the Soviets, and also Estinian vitnesses, and they told how Estonians closed hundreeds of Jews in every synogoge and burned them down. You're right about what was with the Jews in USSR (I'm half Jewish, my mother is Jewish, and my grand-grandpa set in Jail there for a short time for teaching Hebrew), but nevertheless, the Soviets didn't give to Estonians to make pogroms at Jews. By the way, at the days of the Tallin Liberator reburial there were many interviews with Jews from Estonia telling how Estonians murdered their people then. 
All the Jewqish community activities in the 80s and 90s was spoonsored by the Jews, and dont forget in 1987-1989 it was still the Soviet Union. Estonia is desperate for world support, thats why for now the Jews are safe there. Offcourse there are Jews among the writers of the article, but there are also Estonians. M.V.E.i.
