"If you happened to be waiting for your morning coffee at the Starbucks in the Pentagon, you might not be aware that you are surrounded by what is probably the world’s highest density of strategists. Every year, without fail, thousands of mid-level and senior military officers as well as their civilian counterparts will complete some form of professional education that prepares them to be strategists or emphasizes strategic thinking. But what is the true payoff of all the money the U.S. government spends on “strategic education” aside from all those fancy certificates on office walls in Washington DC? A quick look at the last two decades of American global strategy suggests strategic education may simply have become a rite of passage instead of something to be put into practice.

Over the past twenty years, the $6 trillion Afghanistan and Iraq debacles were followed by more regime change in Libya, plunging that country into a civil war (and subsequent proxy war) that rages to this day. Western attempts to overthrow Syria’s Bashar al-Assad were blunted by Russian support, ensuring Assad remains firmly in control. American strategy failed to deter Russia from invading Georgia in 2008 or Ukraine in 2014 and again in 2022. Finally, the hawkish consensus emerging in Washington (i.e. a “New Cold War”?) that conflict with China is increasingly likely—if not inevitable—risks excessively securitizing every aspect of the U.S.-China relationship.

How did we get here? The United States, at least since industrialization, has won its wars (when it’s won them) through the overwhelming application of force and firepower. We have essentially churned out awe-inspiring amounts of war material that we brought directly to bear on clearly identified and traditional (nation-state) opponents who could not match or withstand it. While not necessarily pretty, it was effective. This highly linear approach (action “x” will lead to predictable/intended effect “y”) to warfare became our default strategic playbook.

Unfortunately, such a linear approach is often insufficient in highly complex, interconnected, and interdependent environments. In today’s world, the challenges are much more multi-dimensional and don’t often present a clearly identifiable military center of gravity—never mind one whose damage or destruction can be easily translated into political objectives."
