I had a post about this in 2016:

What if Stalin had demanded all or part of Moldavia west of the Prut in 1945, to become part of the Moldavian SSR? (See
http://en.wikipedia.org/wiki/File:Mihai_1600.png for a map of historical Moldavia.) Indeed, the very decision in 1940 to call Bessarabia (along with a piece of the old Moldavian ASSR) the Moldavian SSR suggested possible future demands on Romania for more "Moldavian" territory.
To be sure, unlike Bessarabia, Moldavia west of the Prut does not have a century-long history of belonging to the Russian Empire, but still, if the Soviets insist that there is a separate Moldavian language (most linguists regard Moldavian, on both sides of the Prut, as simply a sub-dialect of Daco-Romanian--more like an accent than a dialect; one could just as well speak of the Texan language...) logically why shouldn't they apply it west of the Prut as well as east? So Moldavians west as well as east of the Prut will have to get used to calling their language Moldavian and writing it in Cyrillic to differentiate it from Romanian (though Romanian itself was often written in Cyrillic from the Middle Ages to well into the nineteenth century).
"It is true that the Moldavian version of Romanian has a distinct accent and a more Slavic-influenced lexicon than the Romanian of Bucharest, but to a certain extent these traits are shared by all of historical Moldavia..."
http://books.google.com/books?id=n9ycQTKSYdQC&pg=PA13 Very well, then; the USSR demands the unification of all of historical Moldavia (except perhaps for the parts in the Ukrainian SSR) in a single Union Republic...
Why would Stalin do this, when he knows the Communists will dominate Romania? Maybe he thinks even a Communist Romania will be too nationalistic, and desires to restrict its territory as much as possible (at least vis-a-vis the USSR, not necessarily vis-a-vis Hungary).
The most obvious consequence to me is that in 1991 after the USSR falls apart there is much greater demand in this larger *Moldova than in the smaller one (with a proportionately larger Slavic minority) of OTL for union with Romania...
