Russia has armed and supported enemies while we (the US) were at war with them. And you, who claim to be an American, are ok with that?
I don’t know what you are referring to. For one thing, we must distinguish between and Russia Federation and the former Soviet Union.
For another, if you are referring to Russia’s opposition to US illegal regime change operations such as in Iraq, Libya, Ukraine, Syria, etc., then it is perfectly understandable.
