Except for the Russian, nuclear weapon threat, I doubt that they can afford another invasion or war with another country, after what they're experiencing in Ukraine, presently. They thought that the Ukraine, invasion will be a walk in the park, I'm sure that they never envisioned what is happening now, so it's definitely a lesson for them to think twice before considering war again, even if it's a waker country.
With Finland, joining NATO, I believe that Russia, will know their boundary and not consider trespassing with a war with on a NATO member country, because they'll not be facing Finland alone, but the entire NATO alliance. This war has shown that a powerful force like Russia, can be vulnerable, they would have been better off not starting the war in the first place.
The OP has not given much of an argument for this post, I am not sure he has thought over this issue. There are, as of now and while NATO holds, not much of an incentive for Putin to try escalating so directly against a NATO country, even if he tries to make it look like a "liberation of Ruzzians" or some other idiotic propaganda proposal.
You did not understand the sarcasm, I meant that if in 1940 Russia had a reason to attack Finland, today this reason has returned due to joining NATO. Look, Putin said that he attacked Ukraine only because it could join NATO, and the Finns have already joined NATO, but Putin is silent. This means that Putin is lying, and the reason for the war with Ukraine is completely different, namely, Putin wants to restore the empire within the borders of the USSR and started with Ukraine and Georgia.
Putin received another blow from Finland, which became a NATO member, because Finland signed a security treaty with Ukraine. We must remember that Finland has claims against Russia, which took away its territories in 1940, and in the event of Russia’s defeat in the war with Ukraine, Finland will return its ancestral lands.
It will not because in such case Finland would be on its own, without NATO support.
While Russia is no match for NATO, even defeated Russia is too much for Finland to handle. You're not putting a serious thought to it, are you?
How would you expect Russia to react if Finland moved the border. I suspect it would get a steady inflow of volunteers ready to defend the Motherland.
I mean that if Russia loses the war with Ukraine, then it will collapse in the future like any colonial empire, and then Finland will regain its lost territories.
