The Libyans who took to the streets on February 17, 2011 had been called to a "day of rage." A little later, the revolt against Muammar Gaddafi - who at the time was the longest-lived but also the most eccentric tyrant in the Arab world - would be called the "February 17 Revolution." In retrospect, that is the time when the Arab Spring turned into the great war for the Arab world.
The Middle East seems to be undergoing an all-encompassing reset. One at a time, Arab nations are making their pace with Israel. Monarchies in the Gulf are trying to settle old scores. Radical groups shore up old alliances. Iran gets pushed back after over a decade and a half of expansions. The highlights of the 2000s were the outcome of the attack of the al-Qaeda network on the United States, while those of the following decade the result of the Arab Spring. In the East, the third decade is marked by the political will of its leaders.
