Stalin made a bargain with Hityler in part for getting a piece of Polan and Finland he thought was Russian. We know how that ended. up.
The USSR gained a piece of Finland in 1940 and of Poland in 1941. Both pieces remained in its possession after WWII.
Yes, they got piece of Finland BEFORE war, not after.
And piece of Poland they got BEFORE the war, was not really a piece of Poland but a piece of Russia they lost or rather left in WW1.
So you see, Stalin did not grab any land when he had the opportunity (after the war)
And what you I bet did not know
is that Poland and few other countries (other than germany) were grabbing land before WW2 as well
The only land which USSR "grabbed" was Prussia and these islands from Japan.
but these were fair and agreed upon with US/GB/France "grabs"
You're welcome.
