No, it was not unwarranted. First he accuses me of "changing goalposts" and then he does it himself. Next, he complains about being outvoted which is a complete and utter lie. There are countless examples of this type of asshattery.
Plus his notions about "governments should not be bound by the decisions of their predecessors" shows that he has no fucking clue at all of how international treaties work and are upheld. And this is the same guy who consistently rambles on about the great chances his country will get through the same treaties he feels countries should not feel bound by as soon as their government changes. He does not even comprehend how absurdly stupid such a notion is.
