My impression is that the two countries with historically strong ties to Russia are Serbia and Bulgaria. And now Serbia wants Russia expelled from the U.N.!
Bulgaria is planning to build additional nuclear power plants - one proposed site would use a Russian design while the another would use a USofA design. The Bulgarians recently decided to go with the USofA design, partly because of difficult relations with Russia.
So neither of these countries trust Russia now.
Russia launched World War I to protect Serbia against retribution from Austria-Hungary after the assassination of their archduke and his wife.
Bulgaria, even though it was allied with Nazi Germany in World War II, did not send soldiers to fight them on the Eastern Front. They were used almost exclusively against Yugoslavian partisans.
I don’t know if a member of the “Serbian Radical Democratic Party” speaks for historical Serbia anymore than Obama speaks for me.
