Sparsely populated or not Trans-Jordanians were Palestinian at the formation of that country. The outsiders were the rulers. The reason for internal peace since the '70s is that Jordan is an ethnically homogeneous country, and religiously nearly so.

"..a US Department of State International Religious Freedom Report 2006 on Jordan states that: "The Government recognizes Judaism as a religion; however there are reportedly no Jordanian citizens who are Jewish..." This is because Jews are denied 'citizenship' in Jordan, as opposed to Arabs, Muslim and Christan, who remained in Israel.

As to your other comments in your last post to me, you may believe what you will, and define as you will, but I through with playing that game.
