I'm teaching my son Russian and English now as well as the rich culture. I can also teach him to think critically and NOT support war.

I'm sorry your experience has been so one sided, we all have different persepctives.

From all languages in the world that could benefit an individual and help them with future networking/career/etc - like German, Spanish, French, etc - you picked russian?

Please explain why, this is honestly a very confusing choice.
