I don't believe NATO will work in case of direct attack from Russia, e.g. if Russia decided to "denationalise" Poland or Litva. They'll send weapons and may be some limited help, but they won't engage into a full scale war, I don't believe it. There's no point for US soldier to die for Poland territory, especially knowing that it'll cause nuclear response killing his family. NATO is good as long as nobody powerful challenges it. It won't last forever.
