What if that the eastern European countries had enough time to establish them selves that the ould remain independent to world war 2
Huh? Except for Ukraine, they did remain independent until World War II.
I honestly don't get the OP here. Is it (1) What if the treaty of Brest-Litovsk is upheld because Germany wins the war? If that's the case a lot of things are going to change, way beyond Brest-Litovsk! (For one thing there might not
be a World War II, and if there is one it would probably be at a different time than in OTL.) Or is it (2) What if the Entente win but they enforce the Brest-Litovsk boundaries anyway? The answer is that--again except for Ukraine--they actually did enforce borders
less favorable to Soviet Russia. (As George Kennan pointed out in
Russia and the West Under Lenin and Stalin, "The settlement accepted by the Allies at the end of the Russian Civil War--the arrangement, that is, that prevailed from 1920 to 1939--was considerably less favorable to Russia, territorially, in the Baltic-Polish region than that which the Germans imposed on Russia in 1918 [at Brest-Litovsk].")
So basically this simply comes down to "what if independent Ukraine after 1918?" My answer is that it's hard to see this except with the Germans victorious and propping up Skoropadski as a puppet regime. With an Entente victory, the most you could see would be the Poles establishing Petliura west of the Dnieper as they briefly managed to do in OTL in 1920. And given the way they had overextended themselves, it is hard to see them keeping their gains.
