According to Belarusian historian Andrew Savchenko, Poland's new eastern border was "military indefensible and economically unviable" and a source of growing ethnic tensions, as the resulting minorities in Poland were too large to be ignored or assimilated and too small to win their desired autonomy.
Ifølge den hviderussiske historiker Andrew Savchenko var Polens nye østgrænse "militært uforsvarligt og økonomisk urentable", og en kilde til voksende etniske spændinger, og de østslaviske mindretal i Polen var for store til at blive ignorerede eller assimilerede.
