Those precedents were under the idea that Palestine would exist as well under a two state solution which it has been unable to do primarily because of the so called state of Israel. Sure, if you want to just go fair accompli and say their existence on the land and their success in occupying the land gives them a right to exist then go right ahead.
But by international law alone imo they’ve failed with regards to helping to uphold the work done in ‘48 whose goal it was to have a Palestinian state exist alongside Israel. Not to mention, they used terrorism to occupy the land and eventually take it over.
Let’s not even go to the Biblical justifications, on that front this shyt is 100% illegal in the face of their god so that too is a weak argument. To me, they have a right to immigrate and live on the land but as far as I’m concerned that’s Palestine and it’s been occupied by deranged people under a deranged ideology. Their existence is perpetuated by constant support from the west which is really a combination of not dealing with their own racism towards European Jews and having a convenient guard dog to keep their access to energy in the Middle East in a way which best suits their interests.
