Without going into the merits of this war, NATO - which was supposedly a defensive alliance - did indeed attack Kosovo in an offensive.
So NATO has demonstrated they can be whatever they want when the right time comes. NATO intervention in Kosovo to “liberate it” is also being used to morally justify Russian’s invasion of eastern Ukraine, since from a Russian standpoint it’s exactly the same scenario and they are “liberating” the Russian population in those Ukrainian territories.
That’s apparently where 200,000-250,000 Serbian refugees were expected to go after the war.
But my point is that NATO is a military alliance, to call it “defensive” is just propaganda as it has shown it can be offensive too. And there is nothing wrong with simply calling it for what it is, I believe countries should be able to form military alliances, but let’s not gaslight ourselves.
