There’s absolutely no consensus that the legal definition is met, in contrast with another ongoing situation which enjoys wide recognition.
It feels that this is more a geopolitical cudgel, pulled out when the discourse against the US becomes negative. But given the events in the last years, this seems like a lost cause even in the West, never-mind the rest of the world.
