Nope. I can't be sure of anything. However I have as little skin in this game as is possible for a citizen of the world that far removed from the middle east. Israel has to make that call. I think the whole thing is a stinking mess and both sides need to figure peace out. At the same time I am a firm believer that the Muslim world bears most of the blame. If Israel lays down arms completely they die. If the Muslim world stops attacking them there would probably be peace. The one side is genocidal and the other for the most part just wants to be left alone (with some notable exceptions where they expanded in provoking ways into Palestinian areas under their more right leaning politicians).
It's not like this has not happened in the past. The French and Germans fought each other religiously for millennia. Julius Caesar was writing about it in his diaries saying how easy they were to conquer because the constantly weakened themselves against each other allowing him to swoop in. Now we live in a world where its hard to imagine France and Germany ever being at war again. While not exactly friends they have figured out that peace is better than what happened in the World Wars. It took a scary mutual enemy (USSR) to force them to work together and a lot of death but they got there. Hoping somehow the middle east figure out the same. Peace helps the whole lot of them a lot more than the current situation. The general instability of the Middle East drives away so much investment, tourism, etc.
