I wonder if the Russians would be stupid enough to attack during winter, again.
Yes, they would be that stupid.
To remind you: Russia won that ‘winter war.’ To add: Russia crushed Finland in the Second World War (Allied as Finland was to Nazi Germany), as well.
Winter’s over. If the Russians wait until next winter, they’re going to be deploying T55 and T62s. At the rate of loss in Ukraine, Russia will be out of class A troops and down 50% on Class B. Also factor in the sanctions. They cannot produce any high tech military equipment. That will impair replenishment or Tanks, missiles, and aircraft.
Invade Finland? With what?
