Europe buys how much oil/gas from Russia? What income does Russia's economy run on to fund the war? Your argument doesn't make sense. You should see just as many protests over governments funding Russia as we see against Israel if what you say is true.
Yes it's obviously different than directly supplying munitions as uncompensated "aid"
It's also different when then ratio of civilian to military deaths is multiple orders of magnitude higher, and ~5x higher in absolute terms despite Gaza having ~5-10% the population of Ukraine
the only one that europe supplies to uncompensated military aid to, it's ukraine. to russia it simply gives billions of euros that russia later uses to bomb ukraine
about ratio:
- i'll suggest you to take a look at wiki page of siege mariupol. iirc it's up to 75,000 civilian casualties in 3 months
- ukraine actively evacuates civilians.
- hamas said that that well being of civilians is problem of israel and unrwa and actively using civilians as human shields. here is 10 years old analysis that says that it does so in order to shape western opinion https://stratcomcoe.org/cuploads/pfiles/hamas_human_shields....
- ukrainians from day one of war were allowed to seek refuge in europe
- egypt build second wall on border with gaza over past year in order to prevent any refugees crossing and europe talking about any possibility of evacuation of civilians as of ethnic cleansing.
