Let's just act like it's because of COVID that we're shutting down the border, and it'll be okay.
Anyway, yeah, the time of respecting such agreements is over. Finland is now NATO's border wall, the buffer state, and we have to be the hardest SOBs in the entire alliance, the gatekeepers to Europe. NATO can't afford a situation where a weak, leaking Finland is humiliated, because it would then be an embarrassment to everyone involved.
Left-wing stuff, feminist stuff, socialist sympathies towards the East, that has to be a thing of the past. We don't have room for that now. Otherwise we will have to be occupied by NATO forces in order to save face for the entire institution. No more hiding behind "neutrality", we are a clearly partisan military force, and a hostile state against Russia. Presumed weakness on our part could cause a literal WW3 scenario to occur, causing the same sort of chains of events as the invasion of Serbia in WW1 and the invasion of Poland in WW2.
I'm okay with that as long as it's handled well, as long as we don't turn out to be a pushover that gets humiliated by Russia, forcing the U.S. and others to basically take control of our government and military in order to whip it into the kind of shape that is expected of a NATO member that's the most likely participant to see a real-world conflict being waged on its territory. We can only remain "independent" to a degree as long as we're fulfilling our duties. There's too much riding on us now to allow us to be as lax as we've been when it comes to national security.
