In reply to MargieB:
I suspect you are correct in saying there would be a lot of bloodshed as Poroshenko would level the place with artillery rather than let it go, as has been shown by his ruthless bombardment of civilians and infrastructure in the "free" areas.
Including use of banned weapons eg cluster bombs, phosphorus weapons, tactical missiles fired into cities.
To me, coming from Northern Ireland, it seems a crying shame that it has come to this.
