It is tragically apparent that you utterly, and I mean utterly, fail to understand the significance of Bakhmut as it regards the totality of the Ukrainian defensive lines in the south. Drugs are bad, about as bad as staying in stuck on stupid mode.
Mercouris is a disbarred lawyer, not a military strategist or international policy expert. He does not know what he is talking about at all. When that it is pointed out to you go straight to personal attacks and accuse others of drugs and stupidity.
What I understand is Ukraine is making gains from the Oskil to cut off Russia in the northeast, and bit by bit going slow in Kherson. Taking Bakhmut is not one of Russia's high priorities or they would have tried harder to capture it before Mercouris started talking about it.
As for Bakhmut, even if it falls, that will not help Russia much. Look at a online map and zoom in on the area (go on, it won't hurt you).
Russia gets one city, a couple hundred square kilometers of farmland, and runs up to two really obvious and stronger defensive lines, from Lyman-Kramatorsk-New York and Oleksandrivka to Hostre.
Capturing Bakhmut gives little gain for the cost, runs into stronger defenses, while Russia forces are being whittle down in other areas.
That is a bad trade for Russia.
