In 2017, another poll conducted by Pew Research Center found that 69% of Russians, 54% of Belarusians, 70% of Moldovans and 79% of Armenians claimed that the breakup of the Soviet Union was a bad thing for their country. With the exception of Estonia, the percentage of people who agreed with the statement was higher amongst people aged 35 or over. 57% of Georgians and 58% of Russians also said that Joseph Stalin played a very/mostly positive role in history.
