I haven’t had enough time to examine his response, but he again conflates different issues. He treats “international law” as a single thing that either favors one side or not. In reality, international law is a vast set of laws and it’s very easy for a state to be in violation of one part of it and not others. It might very well be true that opening the Khojaly airport would be a violation of international law by Armenia, as Azerbaijan argues. Even if that’s true, Azerbaijan shooting down a plane with civilians is absolutely a violation of international humanitarian law. More to come later.
