NATO is a military organisation which is led by the United States. The war started from expansion threats by NATO against Russia; or in other words, the war is NATO vs. Russia.
As NATO is and long has been led by the USA, the Commander-in-Chief of the USA speaks for them.
(As for why, if it’s NATO vs. Russia, NATO haven’t gone all-in? Because they could very easily start World War III that way, and no one is very keen on doing that.
Oh, and also because they don’t give a fuck about East Slavs.)
Nietzsche wasn’t a nihilist, though. Nor was Heidegger.
And Heidegger diving into the reactionary deep end is incompatible with Nietzsche, whose actual argument re: nihilism was that things like history, tradition, and Heidegger’s “authentic Volk” are without value.
