Europe has nothing to fear from Russia. Looking back at history and how both sides compare demographically and economically it's rather the other way round, and that's one of the reasons why Russia has a huge stockpile of nukes (and also why they always try to derail European integration and rooted for Brexit).
The current 'arrangement' with the US allows Europe not to spend much on defence, which suits political agendas and public opinions, but the price is that the US are in control. This is obviously worth a lot to the US. There's a much bigger picture than the narrow accounting side of military presence.
