Even though my parents' generation was all forced to learn Russian, the current generation doesn't learn it. Even if it would be practical.
Also, Russian may be easy to learn, but it won't be easier to understand than my native Polish to my Czech and Slovakian friends. Interslavic on the other hand would be understood relatively easily.
I just read a chapter from the little prince that's on the page, and I understood it almost perfectly with no training in Interslavic, just with my knowledge of Polish language.
According to Ethnologue, there are more than 100 million Russian speakers outside of Russia. It is the primary language in Belarus and half of the Ukraine (and is known by most people in the country). Almost 7 million people in Poland know how to speak it.[1]
English is probably becoming more of the lingua franca of Eastern Europe, but still, if any Slavic language were to serve as the lingua franca, it would be Russian. It's the Slavic language with the largest international presence, and in contrast to constructed languages, it actually has a large speaker base and significant cultural heritage.
Only because Russia tried to destroy the language and culture of all the nations it occupied. They forced citizens of other countries to speak Russian and not their native languages. It is only the most spoken by older generations while the younger generations of other countries are being raised in their native language.
Given enough time, the Russian language will only be spoken by Russians.
It's also, historically speaking, simply not true that Russia tried to wipe out the languages of the countries it occupied (also, liberated from the Nazis) after WWII. Russian was taught in school as a second language, but there wasn't any plan to wipe out the Polish language, for example.
'Liberated' by invading first you mean. As was done in my country, among others.
I learned Russian basically for irrational reasons. I'm glad I did, but I can't say it is very useful.
As a native of that area in Europe and having lived through some of the traces of russification I can confirm I have a strong bias against the Russian language. When I was a kid, Russian and French were the foreign languages they taught in school and after '89, everyone agreed it was best to switch Russian with English or German. Nobody there wants to learn Russian or immigrate to a Russian speaking country.
Nope.
