First of all, peace on all of you.
Nice question. Well, I think that that is something very far from happening, but I'm just going to mention that during the spread of Islam throughout the World, when the Islamic region/state if I could call it stretched all the way to spain, india, northern africa and other places, all the people from different religions lived in an Islamic rule, which gave them the rights that they needed and had the right to, with of course there representation too in the govt by ppl from them. (Remember, Islam is the religion of God, everyone's God, and whatever our religion or belief, we are all his creations, and killing or degrading any human is like killing of the whole of mankind.) They lived in proper houses just like all the other people, Muslims and others. Jewish and Christian scholars were given high positions in different sects of the govt. etc.... They were left to worship who they wanted to, and were protected by the Muslim army for a tax they had to pay. They lived with dignity and pride which every human being has a right to live in, which has been taken away from our beloved fellow Palestinians.
Muslims, Christians and Jews have lived beside each other on the same land, the land of Palestine from a long time. The Palestinians have been living on this ground, Palestine, for a long time. They cultivated it, built it with their hands, and they made it prosper. Muslims lived with Christians and have lived with them and with Jews, all alongside each other. Invading and taking over a land which isn't yours, and killing it's people and creating thousands of refugees, destroying homes, taking lives, making human beings like any others live like DOGS, I don't think any law or rule or religion allows this, Heavenly or man-made. If they want to live in the Holy Land, they will have to live the way they used to 100's of years ago, alongside each other, with each having a righteous voice in the govt, along with Muslims and Christians, or they can go back to the places they came from, which I personally think is the best thing to do coz they won't do that.
There won't be peace because they don't want it. That's what I have to say.
Whatever your religion, your still a human being, and therefore you have the right to live in peace, and with dignity.
With Peace...
