Only a naive and a completely deluded person would think a nuclear power is simply going to vanish. They are a brutal and an occupying power but they aren't going anywhere. That's a fact, the quicker you accept it the better. All this ''history books, one day'' looks good and dramatic but it only does so on an internet forum but is far detached from reality. Nukes change everything. Hence the reason why India will never capture Pakistan nor will any country dare attack us like they did Iraq.
Whining about Israel is useless as nothing will happen to them. For them to be seriously affected the Arab states and the Americans would together to have boycott them. Even if everyone does, as long the US supports them nothing will happen. All these ban McDonalds or KFC nonsense is only a social media circus. Till the day they are backed by Uncle Sam nothing will happen to them. And their nukes ensure they will never be beaten militarily.
You forget about something called population growth. Israeli Arab population, percentage wise, is expanding at a faster rate than Israeli Jews - and that's including Jewish immigrants to Israel.
If Palestinians end up having an independent state alongside Israel it will only be a matter of time before it becomes fully independent (ie not under military control of Israel and forbidden from having it's own armed forces) and with a greater population that Israel itself- maybe it will take 50 years, or a 100 years, or 150 years ... but it will happen.
Alternatively, if there is no independent Palestinian state, then the status quo can not continue forever. The West Bank will eventually become part of Israel, meaning eventually the Arabs will outnumber the Jews in the expanded Israel. And the Israeli Jews could not forever give themselves greater rights than (eventually) the larger non-Jewish population. Meaning Israel as a Jewish state will be eventually transformed into one that is simply a state like any other.
Think long term, long long term. Think population growth. Think in terms of each and every sect and ethnicity demanding equal rights (may take 100+ years to achieve, but can't be ruled out).
Israel has existed for 70 years. It may exist for another 100 years, for 200 years more.
But that's still a mere blink of the eye in the history of the Middle East. Greater empires have risen, lasted far longer, and then fallen, to be replaced by others even greater that lasted even longer, which also eventually fell.
It's like plate tectonics. Continents move. They move slowly. But they do move. Nothing remains the same.
