Any deal with Putin is not worth the paper it's printed on. It just gives him an interval to regroup, resupply and train up cannon fodder. What we don't know is when he will run out of ordnance, provided of course that our side keeps the Ukrainians well supplied. Unfortunately it seems that rasputitsa is over.
It seems that human wave attacks are the current RF tactic. The Ukrainians need to preserve personnel while exacting a high price.
