This was presnted by Russia in March....
.....”if Ukraine agreed to sign a neutrality agreement that would bar it from entering NATO, recognized Crimea as Russian, recognized the regions of Luhansk and Donetsk as independent, and ceased all military action”.......
As of now the best that could be hoped for is a cease fire and hold present positions.
And even that is remote.
Why would Ukraine agree to any of this when it is winning and has the full support of the entire planet, other than the freak countries like North Korea, China, Venezuela, etc?
