The terrorist attacks of 9/11 plunged the United States into a determined counteroffensive against Osama bin Laden and his al Qaeda terrorist network. This report details the initial U.S. military response to those attacks, namely, the destruction of al Qaeda's terrorist infrastructure and the removal of the ruling Taliban regime in Afghanistan. The author emphasizes several distinctive achievements in this war, including the use of precision air-delivered weapons that were effective irrespective of weather, the first combat use of Predator unmanned aerial vehicles armed with Hellfire missiles, and the integrated employment of high-altitude drones and other air- and space-based sensors that gave CENTCOM unprecedented round-the-clock awareness of enemy activity.

Based on hundreds of oral interviews and unclassified documents, this study offers a comprehensive chronological narrative of the first four years of Operation Enduring Freedom.

In the pantheon of air power spokesmen, Giulio Douhet holds center stage. His writings, more often cited than perhaps actually read, appear as excerpts and aphorisms in the writings of numerous other air power spokesmen, advocates-and critics. Though a highly controversial figure, the very controversy that surrounds him offers to us a testimonial of the value and depth of his work, and the need for airmen today to become familiar with his thought. The progressive development of air power to the point where, today, it is more correct to refer to aerospace power has not outdated the notions of Douhet in the slightest In fact, in many ways, the kinds of technological capabilities that we enjoy as a global air power provider attest to the breadth of his vision. Douhet, together with Hugh “Boom” Trenchard of Great Britain and William “Billy” Mitchell of the United States, is justly recognized as one of the three great spokesmen of the early air power era. This reprint is offered in the spirit of continuing the dialogue that Douhet himself so perceptively began with the first edition of this book, published in 1921. Readers may well find much that they disagree with in this book, but also much that is of enduring value. The vital necessity of Douhet’s central vision-that command of the air is all important in modern warfare-has been proven throughout the history of wars in this century, from the fighting over the Somme to the air war over Kuwait and Iraq.

The defense debate tends to treat Afghanistan as either a revolution or a fluke: either the "Afghan Model" of special operations forces (SOF) plus precision munitions plus an indigenous ally is a widely applicable template for American defense planning, or it is a nonreplicable product of local idiosyncrasies. In fact, it is neither. The Afghan campaign of last fall and winter was actually much closer to a typical 20th century mid-intensity conflict, albeit one with unusually heavy fire support for one side. And this view has very different implications than either proponents or skeptics of the Afghan Model now claim. Afghan Model skeptics often point to Afghanistan's unusual culture of defection or the Taliban's poor skill or motivation as grounds for doubting the war's relevance to the future. Afghanistan's culture is certainly unusual, and there were many defections. The great bulk, however, occurred after the military tide had turned not before-hand. They were effects, not causes. The Afghan Taliban were surely unskilled and ill-motivated. The non-Afghan al Qaeda, however, have proven resolute and capable fighters. Their host's collapse was not attributable to any al Qaeda shortage of commitment or training. Afghan Model proponents, by contrast, credit precision weapons with annihilating enemies at a distance before they could close with our commandos or indigenous allies. Hence the model's broad utility: with SOF-directed bombs doing the real killing, even ragtag local militias will suffice as allies. All they need do is screen U.S. commandos from the occasional hostile survivor and occupy the abandoned ground thereafter. Yet the actual fighting in Afghanistan involved substantial close combat. Al Qaeda counterattackers closed, unseen, to pointblank range of friendly forces in battles at Highway 4 and Sayed Slim Kalay.

Airpower in the War against ISIS chronicles the planning and conduct of Operation Inherent Resolve by U.S. Central Command (CENTCOM) from August 2014 to mid-2018, with a principal focus on the contributions of U.S. Air Forces Central Command (AFCENT). Benjamin S. Lambeth contends that the war's costly and excessive duration resulted from CENTCOM's inaccurate assessment of the Islamic State in Iraq and Syria (ISIS), determining it was simply a resurrected Iraqi insurgency rather than recognizing it as the emerging proto-state that it actually was. This erroneous decision, Lambeth argues, saw the application of an inappropriate counterinsurgency strategy and use of rules of engagement that imposed needless restrictions on the most effective use of the precision air assets at CENTCOM's disposal. The author, through expert analysis of recent history, forcefully argues that CENTCOM erred badly by not using its ample air assets at the outset not merely for supporting Iraq's initially noncombat-ready ground troops but also in an independent and uncompromising strategic interdiction campaign against ISIS's most vital center-of-gravity targets in Syria from the effort's first moments onward.
