Yes, I do see faults in him. He is too naive, and he wants too much to be "accepted into the club". He let himself be fooled and taken advantage of by the West, and especially the Germans and the French, but also the US.
He is too weak when confronting the West, and I do not think he was doing the best thing for the Russian people when he let Minsk drag on like he did.
He is also a bit long-winded and professorial with a tendency to lecture, but that could just be a Russian thing.
Now, if you want to proivide me some documentable evidence, proof of actual crimes or other bad things for which he deserves criticism, then fine, bring it on. But all I ever hear are vague accusations and conspiracy theories for which there is no proof.
