Finland was no NATO and not even the USSR touch it.
If you omit the middle of the 20th century, sure. The Finns declared independence from the Russian Empire in 1917, under the approval of the Bolsheviks’ Declaration of the Rights of the Peoples of Russia. In 1934, Finland and the USSR reaffirmed a non-aggression pact for 10 years. In 1939, after penning a deal with Hitler to carve up Europe between the Nazis and the USSR, Stalin demanded that Finland, who had maintained a stance of neutrality, cede territory for military use and, when they refused, ordered shelling and invasion.
Neutrality or even open trade did not prevent the USSR from invading then, not did handing over nukes save Ukraine from invasion in 2014.
