After ww1 (in an as OTL time line world war)
- Have them more united (the Ukrainians),same for Belarus
- Have them not fight with there neighbours.
- Have Poland,Ukriane and Belarus accept a form of the curzon line.
- Have Romania spend war world one,having here army,been reformed,retrained,and required by the entente,so they see only a limited,involvement in world war one,just a few days or weeks at the end and then have them involved in the Russian civil war.
So we have Belarus,Czechoslovakia,Poland,Romania,Ukraine,Baltic's states (the more the better) fighting the reds in the civil war,so they survive the civil war,both Belarus and Ukraine in the best case scenario.
If things progress as in OTL,we get to molotov-ribbentrop pact where Nazi Germany attacks Poland and Soviet Russia Ukraine (and Belarus if both survive),
Now Poland dose better then otl,since they fight on one front only,they probably still get overrun,but the retreat to Romania is more successful.In Ukraine ( and Belarus) (we don't get the Stalin purges,and famine),and also a Ukrainian (and Belarus).
- The Polish free army will be bigger
- This (the Soviet Ukraine-Belraus war) will also probably skip the winter war,and skip the Soviet ultimatum on Romania (depending on how the Soviets do in the war).(i will the the most optimist in which they are spiked)
- So Finland is neutral,no for Romania,(again the optimist version) they are also neutral ,but they get in a quick war (just a few days) with Hungary in the Slovak–Hungarian War.
so they are also neural in the ww2 (and we add Hungary,and probably Bulgaria and Slovakia).The war as to be quick,so that, together with better Romanian German relations (Romania limited involvement in ww1),and the German need for Romanian Oil there is no war between them,(i know the Nazis are bad,but we will need as much as possible of the central-south eastern Europe (CSE for short),in the right camp for the cold war,and Stalin and Hitler are still friends).
So we get to the Operation Barbarossa,probably same as otl,but with out the involvement of Hungary,Romania,Slovakia.bla,bla bla,the tide is turned (again i will take the optimist path,in which the soviets are not attacking the CSE,and the CSE is not attacking the soviets).But i will be bad and have the CSE,back stab the Germans (when the soviet are in the middle of Poland,and the real evil (and probably abs),we also have deal between CSE and N.Germany and so the war is a fake war,so will have less people dying,we will have the denazification after the war,(and of course the Nazis will put all everything against the soviets),so that after the war there is a CSE is in control of a part of the Nazi Germany empire,that will be Austria,Silesia,Czech Republic,and the south of otl DDR (CSE here is Hungary,Czech,Romania and Slovakia)
(that will be cottbus,leipzig,halle,erfurt,suhl,gera,dresden,Karl-marx-stadt for the CSA controlled ).
So we get to the cold war,Soviets are in control of Estonia,Latvia,Lithuania,Poland and a part of Germany.bla bla,we get to the collapse of the Soviet empire,but in mean time,CSE is somewhere between otl Austria and Greece (when it comes to economic development).
No for the after fall of Berlin wall part,we have a stronger diaspora of Ukrainians and closer to home (more easy to move back and/or invest),a more richer Europe (more money to invest),the CSE is also richer,so there is a close to home place for Ukrainians to work,and return home with out spending a lot of money (weekends and holidays in Ukraine).So we have a Ukraine that is moving to wards the west as early as OLT Poland(the optimist version) or as late as OTl Romania (the pessimist version),so there are as rich as Poland in otl or as pure as Romanian in otl aka monthly average wage 1218 $(Poland) or 753 $ (Romania) (according to wiki
http://en.wikipedia.org/wiki/List_of_countries_in_Europe_by_monthly_average_wage)
Hope this is good enough of an improving over the otl with out to much of an abs.
