Not subjugating them and giving them their land back might be a good start.
You have to remember that this all started with the creation of the Israeli state without the consent of Palestinian people who were living there at the time.

The Jews had been living there just as long. Rehashing the past doesn’t change the facts today. ISIS and their ilk are ruthless terrorists who glorify death, and the Palestinians embraced that ideology, and elected a government whose core mission is genocide of the Jews. The diabolical plan they implemented, with participation and support of the population, has led to the current situation. Hamas kills their own people as much as they continue taking shots at Israelis. They are as evil as it gets, and yet they’ve managed to convince millions that Israel are the bad guys here.
Israel’s terms are reasonable, given what has happened: stop attacking and disarm. If they continue attacking, they will be destroyed. Hiding in residential buildings won’t save them. The leadership, ordering attacks from 5-star hotels in other countries, will not be spared. Jihadists waging war against Israel, and ultimately, western civilization, must be stopped. Their anti-semitic propaganda is just part of their strategy; don’t fall for it.
