Are you referring to Jacques Baud who has been sanctioned recently because he has been working as a mouthpiece of the russian government?
I’ve seen his interviews on YouTube and I’m not sure if he is a Russian asset or just says things contrary to the western narrative. There is a propaganda war.
So what hard evidence that he is working for the Russians?
Jaques Baud is not a "mouthpiece". He has never appeared on Russian state TV and has taken great pains to avoid citing Russian sources in his analysis. The problem is that what he has been saying about the Ukraine war (that the war is not winnable and peace should be negotiated as soon as possible) is dangerous as to European leadership.
In the same way John Mearsheimer and Jeffrey Sachs are mouthpieces of the Russian govt?
Since when is it OK for governments to sanction people when they are lawfully expressing disagreement with Govt policies or views?
