Unfortunately over the decades, the Palestinians have burnt their bridges. The Jordanians lost a Prime Minister, Lebanon never recovered from allowing Palestinians to settle in their country and they have committed hundreds of terrorist activities dating back to Munich Olympics 50 years ago. https://en.wikipedia.org/wiki/Palestinian_political_violence
All this from their inability to adapt to the 1947 UN decision, which would have secured them so much of Palestine in a two nation state. At the same time, many millions of people around the world were being displaced in tough times, e.g. Chinese to Taiwan, Pakistani and Indians to create the new state of Pakistan, Jews from all over the Middle East, East Europeans dealing with the Soviet empire.
Could you imagine if the Moslems of the sub continent had the same mindset as the Palestinian Moslems? The Palestinians have lost every battle since, never losing an opportunity to lose an opportunity along the way. They voted for Hamas in Gaza and squandered millions in their goal of eliminating Israel, rather than build a new Mediterranean centre.
I hope the recent EU Arab declaration can be thrashed out and find a solution to all the suffering. Netanyahu has to go, not just Hamas.
There is a glimmer of light at the end of the tunnel, but Palestinians have to get real, give the extremist mullahs the middle finger, accept the existence of Israel and do their best to create a better life for their children.
They might start by questioning whether they really do get all these virgins if martyred.
