I agree with the person who said it’s not a bad idea to learn the language of your enemy. And Russian culture is fascinating and worthy of study, even if the country is currently being run by a fascist dictator bent on world domination, at the expense and destruction of his own people. But then, that has been a trend in Russian history.

If this bothers you enough to ask about it, have you considered learning Ukrainian instead? You’ll get many of the benefits of learning Russian, and my understanding is that the two languages are mutually intelligible with some difficulty despite the differences.
