Answer :
The Palestinians moved into the holy land after the Israelites left partially because of the haulacost, when the Israelites came back and found the Palestinians they told them to leave, but the Palestinians are all like, " nah bruh, we were here first," and the Israelis be like "what ya talking about bruh? We was here first and God gave us this land!" So the Palestinians are like " you wanna go bro?" And the Israelites go "bring it son!" And that my friends is how a war starts. (That was just a rough translation LOL)
