As the title says, what if the Soviet Union was never formed and instead all territory under Bolshevik control was just one big Russian Soviet Federative Socialist Republic? The Russophone populated areas of Belarus, Ukraine, and Kazakhstan would just be regular oblasts, the non-Russophone areas would be ASSRs or autonomous oblasts/okrugs. The rest of Central Asia and the Caucasus would also be a series of ASSRs and autonomous oblasts/okrugs. These would be drawn on ethnic and geographic boundaries instead of historical o ones, so for example there would be a unified Ossetian ASSR instead of Russian North Ossetia and Georgian South Ossetia. None of the regional entities would have the right to secede. What would the repercussions of this be?
