This is the predictable outcome of decades of Palestinans (I accept their right to self-determine themselves as a separate nation, especially since no Arab country wants them) indoctrinating their children from toddlerhood to hate Israel, Zionism, and Jews.
IMO, two states are the only plausible long-term solution, but to get there, the Palestinians must stop that Jew-hatred indoctrination and instead teach pluralism, acceptance of the other, and a desire for peace, even if they don't get "all of Palestine."
The end result is simple. Getting from here to there is incomprehensibly hard.
