No war is "comfortable", it's a distaster for all involved participants—even the victors.
This is a wrong question. If one day Russia feels brave enough to attack any NATO country, the right question to ask is, "Do we want to fight this war on someone else's soil or on ours?". This is the reason why Europe is so focused on helping Ukraine BTW.
Russia thought so too.
By what metric?
But I saw several people criticizing their relatively high position on this chart given high incompetence and losses.
EDIT: Apparently this website doesn't follow any rigorous methodology. So basically the only thing their army is 2nd in the world is the nominal number of nukes (hopefully most of them don't work).
We aren't that focused actually. France produced close to zero 155mm shells in 2023 because the producer (les forges de Tarbes) couldn't pay its suppliers due to liquidity issues. That could have been solved by a phone call to the national investment bank (BPI) but lasted 9 months because we don't take things too seriously.
Another example is how negligible was the war in Ukraine in the debate about the government budget for the past two years. If we were serious about helping Ukraine we should be spending so much money it would become a priority topic in budget debates, but it's not the case at all.
I'm deeply disappointed about how complacent we have been for the past 4 years.
Yes very much.
That's true, but at the same time it was probably already the case before invasion of Ukraine, and it is definitely the case now.
The main issue is political fragmentation: would Paris and Berlin risk lives of French and German people (soldiers and civilians due to retaliation) to save Vilnius?
But if the answer is true (as obligated by the Treaty of Maastricht, independently of NATO) then Russia stands no chance with conventional weapons against the whole Western Europe, the balance of military, demographic and industrial power is ridiculously lopsided (involving nuclear weapons would also raise the same political question about the French willingness to nuke Russia in retaliation to Russia nuking Poland but if the answer is yes, Russia cannot win a nuclear war either (which everyone would lose)).
