For a peace plan to work (meaning, to end the war once and for all), it will need to get the Palestinians to recognize that the Jews are the indigenous people of Eretz Yisrael and have a right, that they need to respect, to live there with at least complete security and autonomy. It also requires the Zionists to pacify the Arab Muslims, who after all had been the majority in Eretz Yisrael for over 1000 years (along the situation in North America, where those we call the Americans were the majority in much of the country only since the 19th century).
Given the the Zionists and the Palestinians can’t stand each other, a consistent peace plan is impossible. When the Hareidim become a majority, probably in the life time of those know in Heder, the situation might change since the Chareidim could give up some aspects of sovereignty such as having an Israel team compete at the Olympics or have a Zionist flag at the United Nations, as long as our rights to be frum, and secure, were respected.
