Generally, for us ukraine is just another afghanistan mixed with cuba... there are some geopolitical interests and on the other hand, a "foreign superpower" is stepping on the front yard of nother superpower. A short war with maybe a regime change, maybe some lines on the map move, some angry stares, and that's it.
I live in a small eu country (slovenia), and even we helped with afghanistan, and our army is almost nonexistant. Also with syria. Other european countries did the same, lybia, iraq, etc. France is occupying or atleast strongly interfering with a bunch of african countries... and israel-palestine conflict is such a daily thing, noone even remembres it's happening anymore (except the people who die.. well, the people who lose friends and relatives due to it).
And now... instead of angry stares and maybe some basic sanctions, the european economy is getting fucked, we're at the brink of WW3, the german minister directly said that "we're at war with russia", energy prices are skyrocketing, industry is closing down, a food crisis is coming, and instead of a few dead and some destroyed vehicles, we're in six-digit numbers not even couting the wounded. Someone also destroyed the nord stream, it wasn't the russians, and somehow the media has forgotten about that.. the politicians either don't know and don't care who did it (very bad), or know and don't want to tell their people (even worse). And the "normal people" get fucked the most, as always.
Europe could have let putin have this and instead build an inpenetrable defensive wall at the eastern eu border as a response to that... but instead, we're at the brink of WW3. On the other hand, we're sending weapons and replacing them with new ones, we cannot afford... mostly from americans, buying gas at too-high prices... from americans, and getting deindustrialized and demilitarized in turn.
