Oh man I still remember the post that was leaked from russian government webpage on the 25th, a day after russian invaded. It was an absolute hard on about russian imperialism and how they will restore the good old russian empire or something, which included most slavic countries btw. It was taken down in hours but I checked that the addess was correct and legit. No proof of it since it's been a year already and I saved nothing, so if you don't believe it ignore me and please don't spread this since I have no source anymore, but damn if it doesn't paint a clear picture of russia's intent on all of this since way before.
