I generally don't compare anything. Anything. To the Holocaust. But the system of gulags and in particular the Holodomor were both designed to kill large numbers of people. In the gulags, it was done through starvation, unendurable labour, executions, and torture. There is no telling how many people disappeared into the gulags. I'm not even convinced the KGB had a full record. Attrition was very high though. In a sense, the gulags weren't ònly work camps; they existed to cull the population.
