Ukraine is in Europe, it has asked to join NATO, promises were made when they relinquished nuclear arsenal. NATO may begin process but were only going to allow them so far along the application, this may all change, I think states might want to see them in NATO but only my opinion. NATO has not put boots on the ground officially at least, as far as I'm aware. EU has shut airspace to all things russian , they're next in line for Putin's dream, so I'd imagine they'll all be glad to get him dealt with whilst supporting democracy in a sovereign Ukraine
