I know it’s a meme we don’t exist, but we actually do. We’ve also got the biggest and arguably most accurate artillery in Europe.
Homeland defence willingness against a superior enemy is at 83%, one of the highest rates in Europe.
And seeing what we managed in WWII against Russia without allies or gear (now we have both), when the Soviets were well armed, it’s understandable Putin would be a bit apprehensive about opening up a new front on the Finnish border.
