Putin is/has behaved in a way that is totally unprecedented for a Russian/Soviet leader, even at the height of the cold war, no one reduced a european country to rubble and force millions to flee plus threatened nuclear war!
He is 70, wont be around forever, however, he can still cause a great deal of damage and a peace where Ukraine is neutral, the disputed regions become Russian or Russian protectorates is the likely outcome - assuming the Russians really are suffering militarily - which i'm not so sure about, they don't appear to be giving up any territory gained? nor is the constantly shelling reducing, if anything its increasing with their navy using Cruise.
The talks aren't stopping the fighting, so how is Russia using them as a means to re supply?
Cease fire could do this but we are a long way from that.
Difficult relating to the ex generals/ambassadors/dissidents as pretty much all of them have got it wrong so far.
