I see you drank Putin's PR cool-aid. Vladimir Putin's honorary black belt in Judo has already been taken away at the very start of his genocidal war on Ukraine. In fact, his judo skills are extremely overexaggerated as well as his position in the KGB. A lot of people seem to think he was some kind of badass spy? The truth was he was a middle class pencil pushing buerocrat in a low position who nobody in the KGB thought anything much of. Nobody knew him and nobody was impressed by him in the KGB.
Both his Judo and his time in the KGB have been blown waaay out of proportion.
Yes - that is correct Putin belong to a poor family background and his time in KGB has made him a good spy. Also he was bullied by many streets boys so to take a revenge he learnt jodo. His training at KGB was good there.
He stayed with germans too a inducted people in KGB. But Putin is like by Russian that is why he is in power for long.
