Yup the Baltics in particular suffered a lot under soviets. I’m from a town in Lithuania that was basically ethnically cleansed by sending pretty much anyone with education (e.g. my great grandparents) to Siberia with a fucking bag of onions at best and stealing all of our resources; then importing a bunch of russian citizens to take over the area by sheer majority. Ruskies wanted ethnic majority for stable and loyal port cities. Same thing happened with Riga and to a slightly lesser extent with Tallinn.
