Many different solutions have been tried to resolve various conflicts within the Middle East; to date, few have been successful. One issue is that there is no "one size fits all solution". Next, solutions imposed from the outside have consistently failed; any change must be based on the will of the local populace. Thus, in terms of the Arab Spring, Tunisia has rather successfully made a transition to democracy, with a functioning political system using rule of law and legitimate government to improve people's lives. Morocco's king is gradually liberalizing his country and seems to be facilitating a peaceful transition to less autocratic rule. While Libya still has issues of tribal militias causing trouble, the new government should be declared a success -- recovery from several decades under a crazy dictator won't be instantaneous, but democratic institutions are thriving and the economy is being rebuilt with substantial aid from Qatar and other regional powers. For Israel and Palestine, some sort of two state solution seems inevitable, but so far progress, based on foreign-mediated peace talks has been limited. In general, what will work really depends on whether the issues are ethnic, religious, tribal, due to crazy dictators, etc. -- each different issue requires different resolution.
