"The U.S. military is still too focused on conventional warfare."

Blunt instrument: The U.S. military was built to fight and win wars, not rebuild entire nations from scratch.

Absolutely not. In fact, over the past six-plus years of fighting in Iraq and Afghanistan, the U.S. Army has become a counterinsurgency-only force. The notion that there are still some conventional-minded bogeymen lurking in the shadows and waiting for the chance to take the Army back to the 1980s so that it can prepare to fight the Soviets in the Fulda Gap is a chimera.

There are understandable reasons why the Army has become so focused on counterinsurgency: The operational demands of the wars in Iraq and Afghanistan demand it. Counterinsurgency expert John Nagl is thus correct when he calls for "winning" the wars we are in now. Currently, when Army combat brigades go to any of the national training centers for preparation for deployment to Afghanistan or Iraq, they primarily   train on counterinsurgency operations.

Yet the Army has allowed its understandable operational focus on counterinsurgency to dominate its current intellectual climate. Three Army colonels, all former combat brigade commanders in Iraq, warned Army Chief of Staff General George Casey last year that field artillery, because of its recent focus on counterinsurgency operations, had lost its traditional warfighting skills and had become a "dead branch walking."

The group of counterinsurgency experts within the Army and other parts of the greater U.S. defense establishment, moreover, has narrowly selected and employed a certain, situational form of counterinsurgency operations called the "population centric" approach. It's really nothing more than a rehash of the counter-Maoist approaches of the 1960s formulated by Sir Robert Thompson, a British officer in Malaya, and David Galula, a French officer in Algeria. This narrow approach -- known in the current military vernacular as clear, hold, and build -- dominates the Army so much that it permeates the service's professional journals. Now, whenever a problem of instability or insurgency presents itself, it's the only approach that seems to be considered, yet different situations might call for different methods. In this sense, the Army has become dogmatic.

"Small wars are the wars of the future."

Perhaps. But for the Army, the term "small wars" has become synonymous with nation-building. The future of war certainly holds more than that.

Indeed, the dustbin of history is full of mistaken predictions about the future nature of war. An aide to Josef Stalin told the Russian dictator in 1939 that mechanized warfare was not the wave of the future. German armored columns proved that prediction utterly wrong when they came sweeping across the Russian steppes in the summer 1941. Between World War I and World War II, the British saw the future of conflict more in terms of policing their empire rather than major battles fought between land armies. Their muddled thinking led, at least in part, to the near-disaster for the British Expeditionary Force in France in 1940 and its fortunate evacuation from Dunkirk.

More recently, the Israeli Army that stumbled its way into south Lebanon in 2006 received a sharp response by Hezbollah fighters who operated like-small unit infantry. One of the reasons for the Israeli Army's poor performance (as shown by analysts like Mat Matthews and Avi Kober) was their heavy focus on counterinsurgency operations in the Palestinian territories for the six preceding years.

It is true that the future may not necessarily be centered on state-on-state warfare. But future wars will involve fighting terrorists, insurgents, and possible hostile states, or combinations thereof, even if they also involve softer tasks. The Army must organize itself around the principle of fighting with the knowledge that if called on, it can easily shift to nation-building and counterinsurgency, as it has done in Iraq. But doing the opposite -- building an Army that is great at building schools and negotiating with tribal sheikhs but is unprepared to fight at the higher end of the conflict spectrum -- will only ensure that most of the blood and guts will be ours.

"The surge worked in Iraq."

Not quite. It depends how you define "surge." If the surge is defined as follows, then yes, it worked: 1) a set of key decisions on the part of senior U.S. leaders in Iraq to ally with Sunni insurgents to fight al Qaeda; 2) Shiite militia leader Moqtada al-Sadr's decision to stand down in summer 2007; 3) the fact that many areas of Iraq, especially Baghdad, had already become ethnically cleansed by the time the surge started; 4) the addition of an additional five combat brigades, which sent a message to Sunni insurgents and Sadr's militia that the United States did not intend to depart in the near future.
