To be surrounded by NATO is not a problem if you aren’t complete cretins, Austria tells Russia.

Austria used to have an empire until it lost a war and was reduced to its German speaking core. Russia could lose a war, and lose some of its ethnically non-Russian territories but would still remain a large state with widely differing security needs. Austria is not viewed in NATO documents as an adversary and even has security treaties with NATO members like Czechia. In fact, Czechia would do better being surrounded by NATO and having security agreements with NATO nations like Poland. Czechia presents no real contribution to the alliance and it is unclear how NATO contributes to our security.

Also, I don’t think Russia is in any shape to fight NATO, even its European part. Russia has enough trouble dealing with Ukraine that is supported by NATO. That however doesn’t mean Russia should tolerate post-Soviet countries joining NATO, these countries are slated for destruction until they come to their senses. Which is happening to Ukraine right now.
