Writing more than 2,000 years ago, the Greek historian Plutarch gave us an eloquent description of what modern historians now call “micro-militarism.” When an imperial power like Athens then, or America now, is in decline, its leaders often react emotionally by mounting seemingly bold military strikes in hopes of regaining the imperial grandeur that’s slipping through their fingers. Instead of another of the great victories the empire won at its peak of power, however, such military misadventures only serve to accelerate the ongoing decline, erasing whatever aura of imperial majesty remains and revealing instead the moral rot deep inside the ruling elite.
There is mounting historical evidence that America is indeed an empire in steep decline, while President Donald Trump’s war of choice against Iran is becoming the sort of micro-military disaster that helped destroy successive empires over the past 2,500 years — from ancient Athens to medieval Portugal to modern Spain, Great Britain, and now the United States. And at the core of every such ill-fated war-making decision lay a problematic leader, often born into wealth and prestige, whose personal inadequacies reflected and ramified the many irrationalities that make imperial decline such a painful process.
During that demoralizing downward spiral, imperial armies, so lethal in an empire’s ascent, can err by plunging their countries into draining, even disastrous “micro-military” misadventures — psychologically compensatory efforts to salve the loss of imperial power by trying to occupy new territories or display awe-inspiring military might. Although such micro-militarism often chose targets that proved strategically unsustainable, the psychological pressures upon declining empires are so strong that they all too often gamble their prestige on just such misadventures. Not only did such disasters add financial pressures to a fading empire’s many troubles, but in a humiliating fashion, they also invariably exposed its eroding power while exacerbating the destabilizing impact of imperial decline in the capitals of empire (whether Athens, Lisbon, Madrid, London, or Washington, D.C.).
In our moment, when the bombs stop falling and the rubble is finally cleared from the streets of Tehran and Beirut, the impact on U.S. global power of such a de facto defeat will become all too clear — as alliances like NATO atrophy, American hegemony evaporates, legitimacy is lost, global disorder rises, and the world economy suffers.
Let me now turn from the disasters of the present imperial moment to the lessons of history to explore the sort of lasting damage that Donald Trump’s micro-military misadventure in the Middle East might be inflicting on this country’s declining imperium.
