While the New World Order that George H. W. Bush promised in the wake of 1989 never happened, the world was indeed forever changed. But not how things were expected to change. The lack of the Soviet Union was a destabilizing force for two reasons: 1) countries imploded from Europe to Africa to Asia, allowing for civil wars, genocides, fundamentalism, tyrants, and terrorism; and 2) America's dominance turned to arrogance, culminating in George W. Bush's folly of opting to invade Iraq because he could.
The world will change again, but when?
