The EU is not trying to “buy up Ukraine at a discount”, they are pushing for Ukrainian EU membership, which would be mutually beneficial. On the one hand, the EU would gain massive strategic food production and a large experienced military, and further buffer area towards Russia.
EU tried to get its own minerals deal with Ukraine in the wake of Trump demands.

Also Ukraine joining the EU would not make a “buffer”, unless you would argue in terms of first and second class EU countries, with Ukraine being designated to become a second class one. Ukraine currently is the “buffer” as it is aligned with the EU, but not part of it, so the EU does not bear the same responsibilities towards Ukraine as to other EU members.
Well, in Germany we got hammered it in that any likening of anything that was not part of the Holocaust to parts of the Holocaust is inherently antisemitic and a new form of nazism. The Holocaust is supposed to be unique and special forever, as no one is as good at exterminating people like we Germans are and Jews are the eternal victims, hence Israel can’t do any wrong. Conveniently ignoring how other victims of the Holocaust such as Sinti and Roma are still facing rampant systemic discrimination in Germany and also that understanding of Jewish victims being limited to Israelis or people loyal to Israel, whereas Jews who criticize Israel face various forms of repression in Germany.
Now obviously that isn’t the way it is taught directly, but it does involve a sick guilt pride on the one hand and the immediate shut down of any criticism of anything that actually does have parallels to aspects of the Nazi regime and the Holocaust. Or well, that is as long as the criticism is geared towards our allies such as the US and Israel.
Unfortunately the whole debate has been deeply intoxicated and instrumentalized in the “Staatsräson” logic of unconditional support for any and every atrocity, as long as it serves the current Israeli state and its government.
From the best attempt of a neutral perspective: In Auschwitz the Nazis murdered about 1.5 Million people. At its peak there were about 150,000 - 200,000 people concentrated there. From medicinal experiments on humans to random acts of brutal violence there has been all sorts of further gruesome atrocities piled on top of the systematic extermination. So in terms of scale the comparison really cannot come even remotely close.
I do agree with you that these atrocities escalate and escalate quickly, when left unchallenged. The idea that Germany, Israel, the US or anyone other state entity truly learned a lesson of humanity from the horrors of the Holocaust and there would be a certain prevention unfortunately also is wrong. I remember how in school everybody was like “i could have never done this” or “i would have fought against this, how could the people?!” and now we see the same writings on the wall here in Germany again and most people do fuck all, if they don’t already openly embrace it
