I see where you are trying to get with that argumentation based on causality: justification. Thus, back to good/bad.

Still, I disagree on your reasoning for the condemn of ww2 atrocities. From the very beginning german nationalists had a big point against jew ownership and business monopoly. It’s not for nothing that a majority democratically elected the to-be dictator Hitler. It’s the way Nazi party implemented the ‘fix’ and the indifference of the rest of the germans that made up the genocide.

Similarly you repeatedly dismiss a key historical event in the palestinian conflict beginning. The brittish gave palestinian land to jews. Land which housed the majority of the palestinians at the day. How can you expect that to work in any case? Even if Hamas didn’t exist palestinians would have the right to reclaim own land and conflict would be unevitable.

Let’s forget the good/bad reasoning and face the issue from it’s root, which is a mere territorial dispute.
