- Ukraine does not try to forbid Russian language, that's complete disinformation.
- Crimea has been invaded by Russian special forces and annexed by Russia, there is no ambiguity here.
- The fact that Ukraine has a part of its population related to the Russian culture, language, traditions does not justify Russian invading the country.
- Your comparison with Texas is non-sensical. Ukraine has been invaded by the USSR. The Soviet-Ukrainian war happened almost 100 years ago and resulted in a military invasion of the country. Under USSR the Ukrainian movements for independence have been crushed violently and the Ukrainian national identity and cultural identity has been systematically destroyed under Stalin.
