In the globalised world of today people get a lot of information - of course most of it is disinformation, or incomplete or just propaganda from those who are in power.
Russia needs Novorossiya and Malorossiya - at least the part of Malorossiya that is east of the Dnepr river. These parts are not "ukrainian", they never were and they never will be!
The “gas crisis” between Ukraine and Russia was the proximate cause of the present escalation of western attacks on Russia. Thus far, there is no evidence that anyone other than the endlessly suffering Ukrainian citizen will be affected.
