Girls' education is no silver bullet. Iran and Saudi Arabia have both educated girls but refused to empower them, so both remain mired in the past. But when a country educates and unleashes women, those educated women often become force multipliers for good.

Saudi Arabia isn't the enemy, but it is a problem. It could make so much positive difference in the Islamic world if it used its status to soothe Sunni-Shiite tensions and encourage tolerance. For a time, under King Abdullah, it seemed that the country was trying to reform, but now under King Salman, it has stalled.

Saudi Arabia has supported Wahhabi madrasas in poor countries in Africa and Asia, exporting extremism and intolerance. Saudi Arabia also exports instability with its brutal war in Yemen, intended to check what it sees as Iranian influence.

In effect, Saudi Arabia legitimizes fundamentalism, religious discrimination, intolerance and the oppression of women. Saudi women not only can't drive, but are also told by some clerics that they mustn't wear seatbelts for fear of showing the outlines of their bodies.
