The point is, Russia is planning to target only those places that are:
1- Either Russian speaking
2- Have loyalty to Kremlin
3- Have important mineral and energy reserves.
There is simply no other reason. Finland has none of these. It relies on renewable resources technology and therefore has nothing of importance. The only thing Putin will achieve by invading Finland is send an otherwise-neutral Sweden and Norway running into NATO's arms.
As such the Nordic nations are right now contemplating whether to join NATO or to form a local military alliance of all Scandinavian countries with Sweden in lead. Sweden is small country compared to Russia but they are in no means weak. All their military tactics are designed to take out or at least limit an invasion from a much larger country.
Invading Finland will achieve nothing for Putin except weaken support. The only reasons why half the world supported him for Ukraine other than old strategic ties (a different topic altogether) is because it was historically Russian and that Crimeans actually wanted to be a part of Russia; not a case in Finland.
Russia is right now keen on consolidating Russian-dominant areas outside its borders. Access to Crimea gives them critical leverage in Black Sea which they need to keep certain NATO countries in check and to oversee their military progress.
As for using ICBMs, this is not our hosts we are talking about who always mention nukes as if it is a lollypop. ICBMs will be used only in cases where a NATO alliance invades Russian mainland.
Ukraine and Georgia are examples. Instead of using the typical brute firepower that Russia has always used in conflicts, Putin's military is a whole new game.
The Spetsnaz stormed into Ukraine at lightning speed before NATO could even blink and by the time they opened their mouth to cry foul, Crimea was Russian territory.
This highlights a more modern approach of Russian forces. They are building a lean-mean force capable of striking at a moment's notice, destroy their target and quietly move out before anyone can escalate it. That, is the new military model of warfare. One reason is that they are assured of the immense firepower they have as a backup in case shyt hits the fan and a counter-invasion begins.
The VDV and Spetsnaz units are designed to conduct surgical assaults which is going to be the new tactic of warfare.
Norway & Denmark are already members of NATO...
There is no debate regarding an alliance with Finland in Sweden.
Sweden joining NATO is not discussed either.
The only ongoing discussion is whether we should discuss being a member, or not.
but so far the answer is no. Two political parties are in favour, but they are not actively pursuing this.
The main reason for Russia to invade Finland is that Russia may want to control Swedish Iron mines.
The reason Hitler invaded Norway during WW2 was that Brits/French tried to stop the export
of iron ore through Narvik. Finland would be en route o Kiruna.
Then again, Northern Sweden could hardly be claimed to be part of any Zone of Influence by Russia.
Think it would be a hard sell to the rest o the world, and Russia is well aware of this.
Maybe a takeover of the island of Gotland in the Baltics, to "protect" their pipeline.
Still a little unreasonable, because that would piss off the people at the other end of the pipeline.
Soviet and Sweden negotiated the borders in the Baltic Sea and Soviet wanted to count Gotland as uninhabitated.
The Prime Minister of Sweden then asked the Russian negotiators if they seriously believed that his summer house
was on Soviet territory, which made them do a hasty retreat from their position.
