In the case of the United States, it's not appropriate to equate the country with the current regime, since the party in power (Democrat / Republican) changes every few years, and although you may disagree, I do not view the two parties as equivalent or as forming one party.
In the case of Russia, it is completely appropriate to refer to the regime by country name, since Putin has been in power forever.
Anyway, this is a useless tangent. It should by now be clear to you and anyone else reading what I mean, even if it was not initially clear.
