Your antisemitism could not be more obvious.
The truth is that you are a human being and human beings like you can stoop to great evil. Jewish communities have been successful and productive. With a zero sum mentality like yours you figure that it is easier to kill and steal what others have created rather than work to be successful yourself.
Historically Jews were defenseless. When the Arabs attacked Israel they felt assured of an easy victory where they would split the spoils. Jordan would take Judea and Samaria, Syria the Galilee and Jerusalem, Egypt the Negev. Haj Amin’s forces would likely have been left with nothing.
The lesson the Arabs learned from their own history and that of Europe was that Jews could be easily slaughtered. Does the phrase “Khaybar, Khaybar al Yahud” ring a bell? Imagine their surprise when the Jews not only fought back but won.
Palestinian nationalism is inherently racist and based on Arab/Islamic supremacy and the extermination of Jews as opposed to peaceful cooperation. In 2017 Israel offered to help turn Gaza into another Singapore if they would lay down their arms an make peace. Hamas foolishly turned it down. In 2021 the PA was invited to join the Abraham Accords. Never failing to miss an opportunity to miss an opportunity they said “No”. The mentality is that in order for them to win Israel and the Jews must lose.
Not one Arab country has offered to take in Palestinian refugees, not even Kuwait. The Houthis have not offered to give them even temporary shelter. They all know that Palestinians are more trouble than they are worth.
