Is Finland a military risk? Do all European countries have military training requirements?
Most West European countries decided about 20 years ago there will never be war in Europe again, and at the very least no artillery or tanks are ever needed again. Most countries dismantled their armies and gave up on conscription. For example Germany and Sweden used to have quite big trained and well equipped reserves, while countries like Netherlands dismantled their army practically to zero. As an example, after the dismantling Sweden had more generals than tanks.
Not in Finland though. Conscription is still mandatory. About 80% percent of all men are conscripted, though not all go to the Army (about 67% of all men currently), as some choose civil service, are living outside of Finland (until they are 30+), or are deemed to have a too important job for the society. In large parts of the country (outside Helsinki area, pretty much) Army time is seen as the initiation to adulthood, and men are proud to go; as is typical for Finns, they moan about it, but take the training seriously and with pride.
As other countries were dismantling their armies, Finland went second hand shopping. Many countries have legislation that prevents armaments sold to any "risky" countries, but Finland isn't seen as one. Countries were happy to ditch their useless tanks, artillery, missile systems and munitions to Finland, who essentially got practically brand new stuff for the price of shipment.
As a result, Finland has a trained reserve of 900,000 men, by far the best artillery in West Europe (some 1500 heavy artillery (including and heavy mortars) and some 150 HIMARS and other heavy rocket/missile launchers, some 200 Leopard 2 tanks, etc. Finland also never give up on building high quality shelters for the population (all Finns living in urban areas have bomb shelters nearby; yes, everyone).
Why did Finland go exactly the opposite way to the rest of Europe? Because the centuries being next to Russia has teached one thing: Russia always attacks eventually, when they believe Finland has let her guard down. They may be kicked back again and again, but after they have licked their wounds for some decades, they will attack again. The whole Finnish society and ethos, through and through, is built on the idea that when Russia again attacks, they again have to be beaten back. All parts of the society are required to have tested plans how they will function in the event of war (or, as Finns are so politically correct, how to function in exceptional circumstances). And what is more, Finland has learned to stand alone, because nobody ever comes to help when the chips are down.
As such, Finland joining NATO is a monumental change in the the Finnish world. Although many Finns still believe nobody would come to help when the chips are down, but at least in NATO Finland is protected by nukes, so hopefully those thousands of civil shelters will never have to be used against Russian nukes.
To answer your question, no, I do not believe Finland is at military risk. But if Finland ever lets her guard down, Russia will attack. That is why Lauri is doing his military service, to show the guard is not going down this generation.
This is the way.
