For the killings and slaughter to stop of Ukraine's people, somehow Ukraine have to give Russia an exit, if they don't then this will drag on for months and months until Russia deploys even more vast numbers of reserves and flatten the country - yes they are taking mounting losses, but Putin's Russia is spinning so much crap, he could get away with that for years.
The smart middle class Russians are all helping each other to get out, but I wish they'd stay and stand up to him, sadly most Russians outside the cities and the uneducated are all supporting him, the middle classes, the professional classes, the chattering classes are all running away rather than risk 15 years in prison.
