None of which really happened. Since the Russian government went into revolt and then the war ended. Did any substantial reparations get paid? The treaty was signed 3 March 1918; the war ended by an Armistice in November 1918, like 7 months later. Did the Russians pay over anything durinbg the brief time?
The Versailles Treaty was in full effect until 1938, during that time the French invaded the Ruhr and started grabbing stuff. The Germans paid about 21 Billion Gold marks.
And modern economists think the Versailles treaty went too far-
In his book The Economic Consequences of the Peace , John Maynard Keynes referred to the Treaty of Versailles as a “Carthaginian peace”, a misguided attempt to destroy Germany on behalf of French revanchism, rather than to follow the fairer principles for a lasting peace set out in Wilson’s Fourteen Points, which Germany had accepted at the armistice. He stated: “I believe that the campaign for securing out of Germany the general costs of the war was one of the most serious acts of political unwisdom for which our statesmen have ever been responsible.”[185] Keynes had been the principal representative of the British Treasury at the Paris Peace Conference, and used in his passionate book arguments that he and others (including some US officials) had used at Paris.[186] He believed the sums being asked of Germany in reparations were many times more than it was possible for Germany to pay, and that these would produce drastic instability.[xii]
So comparing the Treaty of Brest-Litovsk,- which in reality did nothing, to The Treaty of Versailles (which caused WW2) is bogus.
They went independent. They did not stay as part of the German Empire, and the main reason they went independent is the Russian Revolution, not a meaningless treaty.
