> and aboutour moral superiority compared to those that didn't intervene back then..

Didn't intervene? You act like it was an act of charity. We didn't "intervene" until the germans declare war on us.

> And then look at tens of thousand of people being mass murdered by a genocidal civilization and complain that Spain intervened because...

Spain "intervened"? The genocidal civilization was Spain, not the aztecs. The aztecs didn't wipe themselves out. The spanish did.

> Were we wrong to destroy half of Europe to stop Germany too?

Who is we? Who destroyed half of europe to stop germany?

> Really trilled to know future generation will talk about us as the bad guys because we destroyed German art and books as we stopped a literal mass genocide.

Did we wipe out the germans? Did we wipe out the german language, culture, history, etc? Are you really equating what we did to germany to what the spaniards did to the aztecs?
