Why does it have to be a democracy? Not everyone wants to live in a democracy. Don't other countries have the right to self-determination?
Novorossiya is not a territory - it's a Republic. Imo, the Peoples Republic of Donetsk and the Peoples Republic of Lugansk both have the same right to self-determination that the Ukraine has. So if the Ukraine expects to have the right to self-determination then it must also give that right to those Republics.
The war against self-determination needs to end. It should have ended when the Pridnestrovian Moldavian Republic was formed.
Imo, the will of the people is way more important than terretorial integrity. But that's just me.
