Is that all you have to say? I was expecting a more constructive reply.
Anyway... When you ask for proofs, what kind of proofs are you expecting to see? TT copy? Swift copy? Yeah, right... We both know that it is impossible to provide such evidence, at least not now. Obviously it is not done in a way that can be easily found or tracked, otherwise it would have been published already.
You need to understand who are the interested parties in removal of Lukashenko from the "throne".
In the previous reply I have mentioned few reasons why Russia does not want Lukashenko as next president of Belarus. Who else? Oligarchs? They don't exist in Belarus. The west? Belarus invites Pompeo to Minsk, initiates the establishment of higher level diplomatic relations (appoints ambassador in US for the first time in 12 years), brings oil business and does many other pro-west moves.
Now using deductive reasoning, tell me who is sponsoring the opposition?
