This is sad and needless. I urge Putin to stop the bombing and return to negotiation tables
Indeed, it's sad, it's bad, it doesn't help anybody.
All that Putin has managed to do until now was to make the world see that Russia is not the power they've been boasting/advertising, and that by far.
Unfortunately I don't think that any negotiation is possible as long as his army is still in the neighbor country and as long as he is claiming territories that belong to the neighbor country.
Even more, he seems to have been completely losing the contact to reality, so any "normal" expectations from him are unfortunately futile. I really hope I'm wrong, but this is how the things look like now.
PS. Doesn't this belong to P&S?
