Actually, that isnt a new theory. It was invented by kazakh ultranationalists after the dissolution of the USSR. Its basically a copy of the Holodomor. The famine that hit Kazakhstan at the same time the “Holodomor” happened? Man made to genocide kazakhs. Exact copy. The thing is that, unlike the nazi government of Ukraine, the government of Kazakhstan doesnt endorse or spread this theory. Thats why its not as popular as the Holodomor.
