And you got that information from who?
Don’t know where he/she got it but I got it from Vladimir Putin - he has said it repeatedly. Even brought back the music of the Soviet national anthem and made it the Russian national anthem. You only need to look it up or have paid attention the last 20+ years to what he has said.
Putin has poisoned or killed opponents living outside the Soviet Union. I read the foreign news. He was in Berlin when the wall came down. He was not happy. He is an old line KGB communist
