Which Ukranian ? It is still amaze me many people especialy from West did not see this Russian invasion begin with civil war. Off course looking toward Western Media and Western Political stance it is pictures only as Russian Invasion. All references that used to shown in some Western media of civil war, and Russian ethnics political opposition simply fade away to be shown as only Russian invasion.
Many arguments from Western pundits including some ex military ones that Ukranian fighthing for their home. Well those Donentsk and Luhansks militias also doing the same thing. This is why on early part of this thread, I always talk this is not as simple as foreign Invasion. However off course some will put it as part of Russian propaganda. This include the facts that many part of Southern and Eastern Ukraine is used to be part of Russian administrations.
Significant part of Russian forces in Ukraine coming from Eastern Ukranians especially ethnic Russian (Donbas Militia), which off course can not be uses as indication that most eastern ukranian ethnic Russian will fight for Russian occupations. However some did because many eastern ukranian see the Western parts is part of maiden.
So there are home insentives from those pro Russians. This is afterall begin as Civil War. We can argue to kingdom comes on whose begin steering up ethnics confrontations in the begining. However it will not close the fact there's already ethnics divisions in Ukraine to begin with. You can blame on Russian, as for me I see this as part of unfinish USSR business.
Those Donetsk & Luhansk militia had homes, jobs, votes, representatives in the Ukrainian parliament, schools teaching in Russia, & they'd had friendly Ukrainian presidents, until one of them got too greedy & overdid the corruption. Then Russian provocateurs & organisers arrived, with Russian money & weapons. Remember Igor Ivanovich Strelkov (real name Igor Girkin)? One of the leaders of the pro-Russian uprising in Donetsk & Luhansk - Russian, ex-Russian army officer, & an FSB officer. He wasn't the only one. By an amazing coincidence, those two oblasts suddenly rose up against the government in Kyiv just after that lot arrived. He was defence minister of the so-called Donetsk Peoples Republic for a while, until he fell out with the prime minister, Alexander Borodai - another Russian, currently a member of the Russian State Duma for United Russia, i.e. Putin's party.
Yes, there were divisions in Ukraine, but I doubt they'd have turned into a civil war if Putin hadn't organised, armed, & provided leaders for separatist units, many of the members of which were from Russia. Look at Moldova & Georgia. Isn't it an amazing coincidence that independent-minded former Soviet republics have this happen to them? Belarus avoids it by being a subject state, not truly independent, & Estonia, Latvia & Lithuania by being in NATO.
BTW, by all accounts, the Russian army is conscripting Ukrainians from Donbas to use as cannon-fodder. It can't get away with it in Russia, but its power over the population of the separatist regions in Ukraine is untrammelled. I can't help wondering how many of those conscripts would prefer to be back in pre-2014 Ukraine now. I don't think their lives have improved in the slightest since Putin carved their puppet states out of Ukraine.
