How could Belarus become larger than it is OTL in the aftermath of WW2 and post WW2, without expanding into Ukraine or Russia?
See my thread "'Smolensk and Bryansk Are Ours': Maximum Belarus" at https://www.alternatehistory.com/forum/threads/smolensk-and-bryansk-are-ours-maximum-belarus.421882/ Of course some of the expansions I suggest there are at Russia's expense but other plausible ones would be at Lithuania's expense (Vilna/Wilno/Vilnius) or Poland's (Bialystok, which indeed was part of the Belorussian SSR from 1939-41).
