Rules Based Order

The same people who are saying the Western "rules based order" is dead because of the way Israel is fighting Hamas and Hezbollah also claim Israel stole land from Palestinians in 1948. So - I'm confused -when did this "rules based order" die. It seems like it never quite existed in their minds and yet, it has suddenly just died. They act as though there was some fair system before (that they of course, rejected) and now that fair system has somehow become worse? Incoherent people.
