By that logic, do all countries have a century long statute of limitations to engage in vengeful warfare because of “past conflicts”. Would you justify the massacre of white people because of slavery? Or would you allow native Americans to kill thousands because their ancestors were pushed away from their “land”? You do realize that every single country has fought for its territory - no flag is without sin.
I’m sorry your side isn’t willing to budge on this issue but you can’t engage in this discourse without a nuanced understanding of real history and honest critical thinking. You’re letting others tell you what to feel and look stupid for it.
