Not particularly Israel. What is worth it is not allowing dynastic, socialist--and yes, most Arab countries are heavily socialist--oligarchies and monarchies to prevail. Iran is just a theocracy, a variant of that. Just as Mexico, Central, and S. America have been held back by centuries of state religion coupled to Leftist and radical Leftist, Socialist governments, the Middle East suffers under a yoke of oppression rather than freedom.
Even Israel is relatively socialist but it is tempered there by having a Western-style government with free elections, a sizable middle class with social mobility, and religious freedom. That has allowed it to integrate a sizable Arab and Muslim population that has better economic freedom than if it were in any adjacent nation.
Tribalism and religious differences are tearing Lebanon and the Palestinian territories apart. Those have crippled the monarchy in Jordan and felled the dictatorship in Syria turning that nation into a second Lebanon. Iraq is no different with three warring factions: Kurds, Sunni, and Shiite, one ethnic, the other two religious.
Many of the Gulf States have realized they have to move beyond being monarchies and oligarchies if they are to survive. They've adopted and are moving towards more and more religious freedom tossing off conservative and radical Islam in favor of being secular. At the same time, they are moving towards being constitutional monarchies as a first step towards ending tribalism.
It is nations like Iran run by radical religious fanatics that are the problem in the Middle East.
