This is a national obsession compounded by a sense of paranoia and intensely felt mistrust. Israel has never lived in anything other than an adverserial position and it has become used to it and can't break the habit. this has been compounded further by their role as occupiers. It sets up these hypotheticals, which change according to external circumstances. First, it's "recognise my right to exist"; Whaat kind of question is that? As you correctly state, the international community already did, decades ago, as did the Arab countries and palestinians. So? Well, theenn they change the definitions and the question is "my right to exist as a Jewish State". As to what this means, especially for the 20% of non-Jews in Israel, well, you cant ask that question. So the definitions keep channging as their questions are answered. Thhat is never enough, just reason for another question.
