>>Probably when we started paying nearly all their defense costs against Soviet Russia and they could pour ALL their national wealth into vast government funded cradle to grave social programs
This may come as a surprise to you, but the Finns were never part of NATO. So we weren’t covering their defense costs.
The Soviets in the Cold War era were probably skittish about taking on the Finns due to their Winter War experience in 1939-40.
So when did they become such wussies?
