Of course there are. As there are Arabs and Jews. All of whom shared the land for centuries before the Europeans showed up on their quest.You are wrong first there are no palestinians, they are not an actual ethnic group secondly Hamas is nothing but a proxy for Iran so when they start shiite it will come back to bite them. The area in question is firmly Israeli
You do understand that Hamas was largely created and propped up by Israel to counter the PLO influence...right?
I suggest strongly you open a history book and get familiar with the history of the region.
