Recently, Biden - despite a 'warning' by Erdogan - has acknowledged the Armenian genocide, which was immediately followed by sharp critique by Erdogan. AFAIK, he's the first American president to do so, and among only a small group of NATO countries doing so.
It made me wonder why calling something a genocide is such a big deal, not necessarily only in the context of Turkey but more generally (the first thing coming to mind is China and the Uyghurs)? Clearly this is not up for debate or 'opinion', since there's hard evidence that the genocide happened and who perpetrated it.
I've read this article, and all I could find was that there was essentially "No one wants to piss off Erdogan because Turkey is a strategically important country/partner".
I think I am aware that politics is a nuanced affair and cultures are different, but not acknowledging a genocide for the sake of not offending a political partner seems really... reprehensible to me. Is there something I'm missing?
Edit: I've just learned from here that Erdogan is afraid the Armenian genocide might "undermine the legitimacy of the modern state." How is that? Germany acknowledges the Holocaust and to my knowledge, no one questions the legitimacy of the German state.
