My thoughts on some of these points:1,3) So what? It has not been a continuous country in its present borders since then. Irrelevant.
4,5,6,7) So?
8) I have never heard of Jews praying facing any particular direction. I would say it's common knowledge that Muslims pray facing Mecca. The only ones who would have their backs to Jerusalem would be the ones who happened to be in between the two cities.
9) Rings true to me. I understand that part of the agreement that established modern Israel included lands for any displaced inhabitants of that area. The Arab state(s) involved reneged on their part of the deal.
10) Believable, but I believe most modern Israelis came from other parts of the world, mainly Europe. There would likely have been no call for a Jewish state in the Middle East
