I don’t know where the original Palestinians came from but many are nothing but murderers. The Jews try to give them every concession they can short of their own demise.
Now wait a minute! The original Palestinians were Jewish! The arabs stole the title away when Israel became a nation not too long after WWII. Originally, Palestinian was a reference to Jewish peoples there, while the arabs there identified as Jordanians, Syrians, Libyans, etc.
