The mind of Arab culture is dominance and pride. To be dominated by another is humiliating, and it must be set right by any means.
The Israelis humiliated the Arabs in 1967, a day the Arabs call the Naqba, the humiliation. They observe the Naqba every year.
They are compelled to never stop until they dominate. Now, go read Zechariah 14 to see how it ends.
Naqba was in 1948. From the Arab POV: They only massacred a few Israelis in Gush Etzion and the Jewish Quarter of the Old City of Jerusalem was demolished, which was glorious and all, but then the vile, evil Zionists massacred Arabs in Deir Yassin and Beit Sh’an, which was unforgivable, but even worse, they refused to let themselves be massacred anywhere else. They dared to fight back and mostly win, even conquering the Negev, including Be’er Sheva and Eilat, and build those stinking villages into major cities, and making the dessert of the Negev blossom. A naqba!
