The Baltics - and Poland - had better tighten up their borders and get their respective militaries ready.
Poland is doing just that....and frankly if the Russians try to invade Poland, they will be in for a rude surprise.
The Baltics and Poland are full members of NATO, otherwise they wouldn’t have a chance against Russia. Attacking them would be a bout of insanity, but Russia seems to be just in the mood for that. Rabid animals should be dealt with mercilessly.
