Ah I see European leaders are shocked and dismayed at nazi Russia again without actually doing anything useful.
1. No-fly zone.
2. Heavy bombardment of any and all nazi Russia positions.
3. EU troops in eastern Ukraine.
4. Staggered advancement into western Ukraine, clearing any and all nazi stragglers.
Nazi Russia gets seven days to retreat before this campaign starts. We don't need the Americans to do any of this. If this makes Trump cry, ignore him. This is an EU effort, not a NATO effort. NATO is dead.
