I indeed live in Western Europe, and I'm more concerned with the pissing game between the US and NK than with the NK alone (which minds its own business generally and is isolationist). France had attacked them in the 19th century, and the US went to war with Korea in the 50s (with French support), not the other way around.
Their playing with fire and pissing match with Islam (including pissing whole populations, funding rogue groups, and their favorite regimes in the region) has already costs all of us dearly, including in Europe. Heck, we still have an influx of desperate peoples from every country they destabilized in the past 10-15 years.
Say what you want about colonial European powers, but scum as it were, it still managed to control 2/3rds of the globe with much more nuance and diplomacy than the barbarians at the other side of the Atlantic.
>Well, maybe you will have some empathy if after america falls, North Korea decides to target europe with russia.
I also don't read many fairy tales presented as political analysis.
