In the end of this summer the world shockingly witnessed reports from Kabul on desperate crowds of Afghani people trying to escape on the last flights from the war battered country and the rapidly recurrent Taliban rule before the last US troops left Afghanistan. In the last two decades Afghanistan and Iraq have become the main stages of the United States’ presence in the broader Middle East but its boots continue to be on the ground in several other countries in the region as well. The calamitous withdrawal from Afghanistan by the US does not only mean the long-awaited end of a “forever war” but also the end of Pax Americana, where the US is not going to be a that dominant player in the Middle East than it was before. This retreat will certainly realign the regional balance of power and leave a vacuum which is expected to be filled in soon by other great powers who have long been the challengers of the American hegemony. But why is the US ending these “forever wars” now? How could the dynamics of the region be changed by that? What could be the US’ new posture in the region?
