The melody of their modern national anthem is the same but the lyrics are completely different.
Red is a color of the Russian Federation.
Putin is a nationalist and wants to bring back the Russian Federation back to its pre-Bolshevik glory. He has zero desire to reclaim Latvia, Estonia, Lithuania, Kazakhstan, and Armenia because he has said that control over those republics spread them too thin. Plus he has indicated on numerous occasions that revitalizing the USSR is not practical. He attacked Ukraine because the Ukrainians were committing genocide of ethnic Russians and the US/NATO were putting forward deployed missiles on their doorstep.
The minute you claimed Ukraine was committing genocide against Russians shows you to be either a retard or an Ivan bot.
Russia is already threatening to invade and annex Kazakstan. You need to update your narrative.
