You don't need to 'support Putin' to recognise that 'Ukraine' was, is and always will be a failed state.  It isn't even a nationality; at best it is one of the siblings in the larger Slavic tribal family. 
Just because the US forked out $5bn to affect 'democratic change' ("f..k the EU" by V. Nuland), trying to push NATO closer to Russia's borders  doesn't mean it makes any sense trying to create a fake country, with virtually no cohesive common sense of nationality.
'Ukraine' is squatting on the territory of a now defunct former administrative region of the USSR - it has absolutely no historical claims to any part of that territory, including Crimea.
