A) NATO has had nukes pointed at Moscow for half a century already, so that wouldn't be anything new. B) Ukraine isn't much closer to Moscow than Lithuania is (and hugely father away from Leningrad than Estonia is), so this seems irrelevant. What your neighbours and their friends put on their lawns is none of your business. If it's a lot of stuff usable for defending against arsehole neighbours, maybe in stead of attacking them you should think about what kind of a neighbour you are.
