For years, there was an intellectual battle within Defense and military circles about the effectiveness of air power. Some (predominately Air Force, of course), have argued that Air Power alone is capable of achieving military goals in many conflicts.
Others, have taken the view that Air Power is really only another form of artillery, and that Air Power is only marginally useful as an adjunct to maritime and ground forces.
As with most such debates, the truth is in the middle. Air Power is not a silver bullet. It is most often most effective when used in joint actions with ground and maritime forces. Yet, there are examples, where Air Power alone did achieve objectives. And this is a view shared by most Air Force leaders. Indeed, former Air Force Chief of Staff General Norty Schwartz and I made this argument together in an article in
Aviation Week (sadly behind a paywall) refuting a book that argued that the Air Force should be disbanded. We said:
Farley offers an incomplete history of the effectiveness of
combat air power in recent conflicts. He is certainly correct that early
optimism about airpower as a panacea for modern warfare has proven
misplaced. The strategic bombing campaigns during World War II did not
have the decisive effect that early airpower advocates envisioned. And,
Farley is also correct that the bombing campaigns in Vietnam failed to
accomplish their goal. But Farley’s unstated assumption that airpower can
never be decisive apart from support for ground troops cannot be reconciled
with history. As even Farley admits, without the NATO air offensive in
Kosovo, Serbia would have been unlikely to come to the table.
There are other, more recent examples as well. While
the intensive bombing campaign against Iraq known as Operation Desert Fox in
1998 was heavily criticized at the time as ineffective, we have since learned
that the operation was largely responsible for Saddam Hussein’s decision to end
his WMD efforts. U.S. military operations in Afghanistan in 2002
and in Libya in 2011 were largely exercises in air power. And had we
intervened in Syria, the focus of our efforts would have been on the use of air
power. Simply put, airpower is not a panacea that can replace the need
for ground and naval forces–history has made that point abundantly clear–but in
some circumstances, combat air power is an indispensable tool of national
power.
I was therefore fascinated to find a great analysis of the power, and limits, of the use of Air Power in the war against the Islamic State, by Daniel Byman of the Brookings Institute. First, Byman notes that Air Power has been effective in degrading the capability of terrorist organizations. In addition to killing leaders, Byman notes that the use of Air Power limits a terrorist organizations capability:
Training on a large-scale is harder, if not impossible, as
large gatherings can be lethal. Group leaders’ influence wanes, as they must
hide or remain incommunicado. Trying to organize a kids’ soccer game, let alone
a global terrorist network, becomes almost impossible if you can’t use phones
or the Internet regularly. The indirect effects also matter. Islamic State
leader
Abu Bakr al-Baghdadi has been laying low since U.S.
military operations began, diminishing his charismatic presence from Islamic
State propaganda and, presumably, disheartening his beleaguered troops. Abu
Mohammad al-Adnani, the spokesman who headed the group’s external operations,
was also charismatic and inspired terrorists around the world to attack—and
eventually the United States tracked him down and
killed him in an airstrike.
Yet, in this context, Air Power has a serious limit. We can degrade and destroy the enemy, but unless we address governance issues that allowed ISIS to arise in the first place, we can prevail in the battle and still lose the war:
Nor does air power address the biggest long-term challenges
in fighting the Islamic State:
governance. The United States has proven again and again
that it can dislodge terrorists, insurgents, and forces loyal to local despots.
Filling the vacuum so that they don’t return is much harder. The terrorists
often come back, or, at times, chaos rules. Neither outcome is an improvement
for locals, and new terrorist groups can breed if there is no government to
keep them down. You can’t provide that governance with a drone.
Moreover, for air power to be effective, you need capable
local allies. Their forces can provide the necessary intelligence to find and
target Islamic State fighters. In addition, when they advance, they force
Islamic State forces to mass—making them vulnerable to air power. If Islamic
State fighters stay dispersed and hidden, then forces on the ground can root
them out. Local forces can also fill the vacuum after victory, ideally
establishing a legitimate government and preventing the terrorists from
returning or new extremist groups from arising.
The
article is well worth reading. You can find my own expanded thoughts on the uses and limits of air power, in this
book review.
