The Russian SFSR was not tiny. It included most of the territory in the Tsardom of Russia, around 1700:
I’m guessing the Russians (or at least Russian leaders) want all the territory it held under the Soviet regime and all the territory it held under the Tsarist regime. And probably some territory if feels they should have held under those regimes. So Ukraine, Belarus, Finland, Poland, Afghanistan, Alaska, Manchuria, and Turkey are all on the table.
I should have been more clear that it was a “tiny” republic. In any case, as Little_Nemo observes, look at what’s left on the map!
The reading is probably “over” rather than “to”, the cumulative size of what they consider “Russia” for the past four fifths of a quart of vodka millenium. Or, “any place than any ethnically/linguistically Russian person has called home in the past couple baktuns.”
What is Russian for Lebensraum?
жизненного пространства, zhiznennogo prostranstva is the direct translation but I think Greater Russia (Великая Россия) is more “Manifest Destiny” type of concept that you’re talking about.
Irredentism is a hell of a drug.
