What does that even mean. There are tons of ethically Russian people -- at least four that I know of in my extended social circle, one of whom has already died -- proudly claim Ukrainian nationality (if not ethnicity) and were among the first to take up arms and volunteer to fight against Russia. If borders are malleable so too are ethnicity and nationality malleable.
