Sweden and Finland do not pose such a threat. Finland is on the border too but a much less exposed portion.
The costs of this invasion were clear from the outset. Russia isnt going into this thinking it will come out stronger and ready to conquer the world. It's a fairly desperate and high stakes ploy to shield their jugular.
This is more a nationalist Russkiy Mir/Russkaya Zemlya kind of mental jerk, as evidenced by that article that RIA Novosti published (and then pulled)[0]: if they don't take now what they consider theirs(Ukraine), then they never will if they join NATO. To have one people split in two (though Ukrainians largely disagree) is unacceptable to them.

Ah, good to hear you know more about how Russia sees these things than they do themselves.
Because Stalin sure didn't seem to see it your way in the winter of 1939.
Aren't you beginning to sound ludicrous even to yourself by now?
