It was only a joke, незрелые укол. You don't have to take everything seriously.
And anyways, the only reason why Finland did 'good' in the war was because its army had experienced soldiers when Stalin had executed all of his generals due to his paranoia. The Axis was also on Finland's side defending the northern border. After the continuation war in 1942 or so, towards Finland keeping its independence the Soviet Union demanded Finland to take care of all the national socialist's in Lapland which resulted in a war that ended in most of the Northern Finland being burned down to the ground.
And i never said that "Finland won" or anything. If you look at the statistics you can see that in a battle in which Soviet Union had about four times bigger army than Finland, it also lost four times more soldiers and tanks and so on when Finland lost much less.
If you actually got all worked up about this, consider getting some meds to help with that patriotic pride that blinds your sight of "obvious joke".
