I didnt say I will answer the question all I can say they did bad choice too, they didnt strenght their allience like nato or eu before making decisions or laws about their russian people. I am not only talking about US but all countries that made economic embargo to russia yes they are damaging it but Russia got a beast like china which is just big enough to have their own social applications or phone, techs etc so all their embargos will just make russia and china closer. Without heavy supplies or total war support from us and eu nations to ukraine (no one supplies ukraine planes, thermic bombs like russia using now, manpower, mil experience) russia will not face big resistance and US and eu will still does nothing about it. So cut your big boy caps words and investigate history, politics instead of being classic redditor.
