Baltics and Poland are only threatened by Russian TV commentators and sometimes Dugin, who depending on the mood of the day says that Poland and the Baltics are not part of the Eurasian project, and on other days says that Estonia is in the German influence sphere (!) but Latvia and Lithuania are in the Russian sphere. These people foam at the mouth and have little influence.

I have never heard any serious Russia politician claim that the Baltics or Poland should be invaded.

Ukraine and Georgia are fundamentally different (for them), which is why they always have been red lines as pointed out in the Burns diplomatic telegram.
