Unmanned combat aerial vehicles (UCAVs) wonder weapons of today's wars. UCAVs have been credited with striking convoy carrying Moammar Qaddafi; killing al Qaeda's Abu Yahya al Libi and Anwar al Awlaki; eviscerating Taliban's ranks and other militants in Afghanistan and Pakistan (AfPak) theater; and hitting targets from Asia to Africa--all without putting pilots in harm's way. The drone revolution promises many benefits, but there also drawbacks to this nascent unmanned air force--drawbacks that few policymakers have contemplated. Just as drone detractors need to acknowledge what UCAVs bring to table, UCAV advocates need to acknowledge negative implications of drone warfare. Today and Tomorrow Whatever one's view of UCAVs, appeal of drones is understandable. As an Air Force report concludes, drones are not limited by human performance or physiological characteristics ... extreme persistence and maneuverability benefits. (1) In other words, drones can handle what humans cannot--G forces and speed, tedium and boredom. Among other intrinsic benefits of drones: they deprive enemy of human targets; they don't get tired or thirsty or hungry; they relatively inexpensive; and with coming of nuclear-powered drones, they offer possibility of nearly endless above-target operation. It is no surprise, then, that drones beginning to dislodge manned aircraft from crucial role they have played in warfighting since World War II. Consider some of evidence: * has been a 1,200-percent increase in combat air patrols by drones since 2005. (2) * In past decade, US drone fleet has swelled from 50 planes to 7,500, though vast majority of these drones not UCAVs. (3) Still, drones represent 31 percent of Pentagon's air fleet. (4) * America's unmanned air force--including drones deployed by military and CIA--has struck targets in Pakistan, Iraq, Libya, Afghanistan, Yemen, Somalia, and Philippines. (5) UCAVs so central to US efforts in Afghanistan and Pakistan that some observers have dubbed this front of antiterror campaign the drone * Referring to F-35 Joint Strike Fighter, then-Joint Chiefs Chairman Admiral Michael Mullen declared not long before he retired, There those that see JSF as last manned fighter or fighter-bomber. Raising more than a few eyebrows, he added, I'm one that's inclined to believe that. (6) Two factors accelerating use of drones: public's growing distaste for US casualties and Pentagon's shrinking share of budget. Regarding former, it pays to recall American people's tolerance for casualties has waxed and waned over decades. They obviously have had a high threshold for casualties at times. For example, despite far higher casualty levels than recent conflicts, public support remained high throughout World War II and during much of Vietnam. However, that changed dramatically after Vietnam. The result was a quarter-century of push-button, almost-bloodless wars (at least for Americans), each conditioning American people to expect less bloodshed than previous conflict. This, in turn, conditioned political and military leaders to deliver more push-button, bloodless wars. The 9/11 attacks briefly broke this cycle, having an effect on American public not dissimilar from attack on Pearl Harbor. Consider a CNN poll conducted after 9/11 asking Americans if they would support military action even if it meant 5,000 American troops would be killed. As a sign of their grim, if ephemeral, determination, 76 percent said yes. (7) Of course, those attitudes have shifted, predictably, during what one observer calls the wars of 9/11. (8) Land wars in Afghanistan and Iraq have been lengthy and costly, with 4,485 American troops killed in Iraq and more than 2,147 killed in still-unfinished Afghanistan war, America's longest shooting war. …
