As far as recent statements from other sources regarding protectorate see post 33:

Okay, this merely the opinion of a Belarusian political commentator. Look at all the stuff our commentators say on MSNBC, various radio shows, etc. He does not even claim any Polish official has said this. He’s just mouthing off, stirring the pot.
As pro-Russian, he says stuff like this the same way some lib commentator on some lib show spouts pro-lib anti-conservative opinions, like white Republicans want to do away with black people or Trump supporters are against “democracy”. Doesn’t make it real or true.
Okay, this appears to be his whole speech (?) at the Warsaw conference. I can make out some of it, but don’t speak Polish. Never studied it or tried to learn it. So I have no idea what all he said. It’s available on the Polish government website, so one would think if he actually said that about a protectorate, the Russians would be trumpeting it far and wide. They certainly have access it it. They got the interwebs, too.
Maybe dfwgator and/or Cronos can check it out. As I understand it, they do speak Polish.
