Moving the Wagner to Belarus could be a tricky move to attack Ukraine from the north:

Former Chief of Staff of the British Army, Lord Richard Dannatt - that moving the Wagner to Belarus could be a tricky move to attack Ukraine from the north:

If you were in command of the Ukrainian army, what would you be worried about right now? About the advance of the counter-offensive in the east, or, as you just said, about the potential threat from the north, from Belarus? I would definitely make sure that I have good control of the situation in the north, in the direction from Belarus to Kyiv.

The Russians have taken advantage of this in the past, and quite devastatingly. And it is quite possible that they will repeat. Under the command of Prigozhin and the troops that he now has. As I just said, we don't know how many troops he has at his disposal, but that flank needs to be watched very carefully. And make sure that there are mobile units that could repel an attack from Belarus.
