Russia is not going to give NATO access to its military installations if its sanctioned.
The loser of course will be the West over an issue its not going to go to war over.
Mutually beneficial relations will suffer because NATO needs to “show the flag.” As if Russia cares about NATO strutting its manhood.
NATO strutting its manhood would involve large-scale military exercises near Russian borders and ICBM tests. (Come to think of it - isn't that what Russia was and has been doing before and during its current military adventure?) These are just limp-wristed pro forma sanctions, done so Obama can't be accused of completely ignoring the Anschluss under way.
