Well, the Palestinians didn't choose to be driven from their homes and massacred in 1948. They didn't choose to have their land stolen from them in the West Bank and bought/bullied out from under them in parts of Israel. And another talking point that I plan to address in this upcoming article, you cannot turn a blockaded enclave with no control over its international waters or airspace into a prosperous, flourishing utopia.
But sure, they chose to fight. And whatever views you might hold about Patrick Henry's, "Give me liberty or give me death," they way they've fought, and the extremism they've embraced, have obviously caused them, and innocent Israelis, a great deal of pain over the years.
One last point. You don't need to "indoctrinate" people against the occupying force that drove their grandparents from their homes, that steals land from their relatives in the West Bank at gunpoint, that trapped their parents in an enclave with next to nothing, and that is currently blowing their homes, and their children, to pieces.
There is more than enough hatred to go around in Palestine and in Israel without any special efforts at indoctrination. Think about the kids rowing up in Gaza now. Think of them have lost their parents or other members of their family. How many of them are homeless, how many of their brothers and sisters have had limbs blown off. Seriously, if that were you, how much "indoctrination" would you require to hate the people responsible? Because speaking honestly, I wouldn't need much at all.
