A so-called "2 state solution" is an oxymoron. A state, by definition, has a sovereign monopoly on violence. Your 2 states already exist and they are inevitably at war.
The phrase was dreamt up by Western Israeli allies to promote an oppressive pipe-dream border arrangement that was not even remotely acceptable by any reasonable standards. Only propagandized westerners even speak of it.
This is done so the Western media can frame Palestinians as uncooperative.
