The relative global decline of the United States has become a frequent topic of debate in recent years. Proponents of the post-American view point to the 2008 financial crisis, the prolonged recession that followed and China's steady rise. Most are international relations experts who, viewing geopolitics through the lens of economic competitiveness, imagine the global order as a seesaw, in which one player's rise necessarily implies another's fall.
But the exclusive focus on economic indicators has prevented consideration of the geopolitical implications of a U.S. domestic trend that is also frequently discussed, but by a separate group of experts: America's ever-increasing rates of severe mental disease (which have already been very high for a long time).
The claim that the spread of severe mental illness has reached "epidemic" proportions has been heard so often that, like any commonplace, it has lost its ability to shock. But the repercussions for international politics of the disabling conditions diagnosed as manic-depressive illnesses (including major unipolar depression) and schizophrenia could not be more serious.
