War and violence decoupled from strategy and policy—or worse yet, mistaken for strategy and policy—have contributed to perpetual war, or what has seemed like 15 years of “
Groundhog War.” In its wars since 11 September 2001, the United States has arguably cultivated the best-equipped, most capable, and fully seasoned combat forces in remembered history. They attack, kill, capture, and win battles with great nimbleness and strength. But absent strategy, these victories are fleeting. Divorced from political objectives, successful tactics are without meaning.
In theory, we fight wars to fulfill a political purpose and to achieve objectives by aligning the means and methods of war toward that purpose. In theory, the purpose of war is a better
peace. In theory, there is no difference between theory and practice, but as history has shown repeatedly, in practice there is.
The purpose of war is to serve policy. Unchecked by reason, unguided by policy, the nature of war is to serve itself. When war and violence serve each other, absent strategy, it is fruitless killing. World War I was a conspicuous example of war for war’s sake, and serves as “an excellent
cautionary tale about the dangers of carelessly blundering into a pointless and catastrophic conflagration.” The war in Iraq and the strategic stalemate in Afghanistan, are simply contemporary examples of the same.
