There are very few Russians in Poland, or very few that would admit to it.
Right. But Estonia and Latvia are small countries with a lot of Russians. In the end it will be about geography. Poland is next to Germany. Estonia and Latvia are next to 150 million Russians.
In the end it’s also about why Russians in the Baltic countries choose to STAY there and why some Russians fed-up with the Putin conditions contemplate MOVING there.
Because they want European freedoms, perks, economic opportunities (especially in the field of technology) and living standards.
