I still don't see Finland joining NATO, yet. The government holds the opinion of military officials in high regard and the official stance of the military is that "every country, in principle, should take care of its own national defence." This has been unchanged.
Although, if there ever was a time and will to join NATO. it is right now. It just has to be done quickly enough that the Russians are not able together forces on the Finnish border to put pressure on the government. Currently, a significant portion of Russian troops that are generally garrisoned at the Finnish border in the Leningrad area have been pulled into Ukraine.
