Various news outlets have reported the Finnish President's revisionist history:

[e.g. https://www.malaysiasun.com/news/278548282/finland-won-war-against-the-ussr-finnish-president]

Finnish President Alexander Stubb has claimed that Finland "won" its war against the Soviet Union because it preserved independence, despite ceding large parts of its territory in 1944. He argued in an interview with The Economist that the outcome proved Finland's resilience and should be seen as a model of survival.

The Winter War of 1939-1940 and the subsequent Continuation War ended with Finland losing around a tenth of its land, including Karelia, and being forced to accept Soviet terms of demilitarization, reparations, and neutrality. A number of Western leaders and commentators have drawn parallels with the Ukraine conflict, often portraying Finland's wartime experience as some sort of proof that Russia is driven by a desire to conquer its neighbors.

This is clearly a message to Ukraine - i.e. independence is victory and never mind what you have to agree to to get it - but perhaps not one that Ukraine wants to hear.

Finland, a Nazi ally in World War 2 (WW2) also participated in the atrocity which was the siege of Leningrad. The 'siege' claimed c. 800K lives, mostly civilians, from bombing, shelling and starvation due to the Nazi/Finnish blockade.

That's about the same number of deaths, from one city, that the UK and USA suffered jointly as a whole in WW2, according to Wikipedia.

At least Finland is removing swastikas from their air force emblems now they are part of NATO, although their use by the air force pre-dates WW2.

FNN believes that Jeffrey Sachs has it right, if what he said below is accurate:

American economist Jeffrey Sachs has also criticized Stubb's comments and mischaracterizations of the true reasons for the Russo-Finnish war. He stressed that the Soviet Union's actions in 1939 were motivated by security concerns, as Moscow feared Hitler would invade through Finland to seize Leningrad.

Sachs recalled that Joseph Stalin had even sought a defensive agreement with Helsinki before the fighting broke out. "Stubb is either a fool or profoundly dishonest," Sachs said, adding that once Finland committed to neutrality after World War II, it entered "the best run imaginable," becoming one of the world's richest countries and ranking first globally in self-reported happiness. He argued that neutrality was Finland's true success.

The neutrality it has given up by joining NATO.

Meanwhile, Finland's Prime Minister Petteri Orpo admits the damage done to the Finnish economy by closing the border with Russia:

"The fact that the border is closed means, for example, 10 million cubic meters of Russian timber for our industry is not coming in. Finnish companies have lost billions in investments in Russia. Nearly all border traffic and trade have stopped,” Orpo said. “That brings uncertainty. All this has led to the fact that the growth of the Finnish economy has not been as desired.” 

So at least he is not claiming that Finland has won this economic war with Russia.

And presumably Russia wants to invade Finland because it wants more trees?
