Somethings are better left alone is not a motto very often heard from would be peacemakers at the U.N. They need to feel that peace is making progress or there is risk they could attempt further pressures against Israel. There is a need to decisively end the conflict because the risk of continued conflict means continued pressure by world governments and international trade pitfalls. Conversely, resolving the Palestinian matter, would remove the pretext for such pressure.
Post Iraq War, there is a mood of proactive resolution of conflicts by multilateral negotiations via the U.N. whether or not such deals are effective, there is a desire for deals at all cost. The fact that U.N. involvement in a conflict may only makes things worse, does not prevent them from wanting to try and try again even harder. The fact that belligerent nations like to ride the wake of U.N. movement in and out of a troubled region does not seem to make the U.N. change policy either.
The only thing that would change U.N. policy toward Israel, is that a legal peace plan is in place, even if only as a long term process. If Israel were able to implement a legal One State solution, in a way that got many Palestinian Arabs on board, even if it was not a Two State Solution, it would remove U.N. pressure as we know it today. This is politically viable as the naturalization amnesty would be seen as a boon by many Palestinian Arabs in the territories today. Terrorists would then become a negative thing again to the U.N., since it would be the Palestinian Arabs themselves who would suffer if such a One State solution was NOT implemented.
The key parameter is that a One State Solution be comprehensive and whole. If even one scrap of contested land remained afterwards, the pressure at the U.N. would not likely stop. The only way to end this is to do so conclusively. The full annexation of Judea, Samaria and Gaza with the naturalization of Arabs who are willing to display loyalty to Israel, and the filtering and rejection of terrorist elements among them.
Then there would be no pretext for political pressure and financial boycott. No more potential for chaotic nations using perceived failures at the U.N. as part of a pretext for war. No more need for perpetual hasbara, just to try to have fair and balanced reporting. Hasbara would then be more about encouraging travel and aliyah than the bitter struggle for international fair play in politics and trade that it is today.
Then Israel could save the Arabs of Judea and Samaria from their despotic leaders, distance terrorists from Israel's heartland, and clean away the current tarnish to Israel's reputation all at once. In other words, have true peace at last. May it soon be so, by the grace of God.
