Does the rest of the Slavs speak Russian?

In former USSR countries a lot of people speak it but in other countries no

I am Czech and I speak Russian well, but it is because I am interested in learning languages. Young Czech people usually do not understand Russian, but my parents do and they can say something simple.

Also, there are some countries where Russian may be useful too. For example, Israel (20% of the population are Russian speakers). But most of them are immigrants from USSR or their children/grandchildren.

Not all Slavs speak Russian, and in the same time Russian-speakers are not Slavs only. If we're talking, for example, about Czechs, Croats or Poles - most of them do not understand Russian. Most of the Ukrainians do, especially in the East of the country. In Belarus Russian is an official language equal in Belorussian, and I doubt there is a Belorussian who cannot speak Russian.

 

And as I said, there're also non-slavic countries, where Russian will be useful. For example, about 70% of Georgians can speak this language. And in Kazakhstan and Kyrgyzstan it even have an official status. Moreover, they say, that at the North of Kazakhstan most of the people speak Russian, but do not speak Kazakh!
