Putin doesn't want Ukraine to be a part of Nato, doesn't want things on his borders that could be a threat. He's been complaining about it for years and years and been ignored so he's trying to do something about it.
But that's a "him" problem surely?
If Ukraine wants, or wanted, to join NATO/UN/EU then it's completely in their purview to do so. Having "icky feels" towards NATO, and co, doesn't give a country the right to dictate what a neighbouring independent democratic country can and can not do. Nor does it allow them to invade because of said "icky feels".
