Estonia and Latvia would be more susceptible targets with 29.6% and 33.8% Russian speakers respectively. Poland has almost zero Russian speakers. %0.1. No Russian allies there. Pure political maneuvering.
No the Baltic countries of Estonia, Latvia and Lithuania were invaded by Russia in 1941...
they are not friends of Russia and have Russian speaking people mainly because the “white Russians” fled there during the Russian Revolution, 1917...
the communist Russians came in in 1941 and started kidnapping people out of their homes and they were never seen again...mostly people with that previous Russian background, connection etc...
In fact, it has been said America has more Spanish speaking citizens than Spain itself...
