Russia's Concern About Sweden and Finland Joining NATO

Ukraine gains the status of say Austria during the Cold War or Mexico today. Would Russia agree to that? It's only one way to find out. As long as you insist on not trying, can't find out. If invasion was triggered by Ukraine moving towards NATO, would Russia not have attacked Finland and Sweden about around a year ago? There has never been the slightest indication of any Russian concern about Sweden and Finland. The reasons for Sweden and Finland moving to join NATO have nothing to do with fear of a Russian attack, which has never been even conceived.
