It's more of a solution than the so called "two state solution." I'm sure there were people like you who said the same thing about whites and blacks living as equals in south Africa with a democratic vote.
I won't dignify the 'people like me' comment with a response.
The two situations are incomparable. South Africa was a single state saddled with a racist government. The government changed, and hallelujah for that, but the state remained intact.
You want to 'uninvent' the state of Israel and make it magically disappear, assuming that everyone would then live happily ever after. Pretending that is remotely possible in the real world is pure fantasy, and offers no hope of a solution to anyone because it will never, ever happen. Why? Because you'd just be replacing one set of insurmountable problems with another, one set of displaced people with another, one spurious justification for pointless murder with another. The killing would never, ever stop. And in the meantime, while you indulge in this impossible fantasy, in the real world the killing will go on. And on. And on.
Real solutions are much harder to achieve and require genuine compromise from all sides involved and a basic commitment to stop killing each other as the absolute minimum. That's not impossible to achieve, as Northern Ireland demonstrates to us on our own doorstep, but the combatants in Israel and Palestine seem a million miles away from any similar kind of compromise.
