After the collapse of the Soviet Union, it dominates the world in a manner not seen for least 150 years, and perhaps much longer. Eventually, and predictably, it was eclipsed by several of them. In contrast, the United States possesses not only the ability to intervene everywhere, but the ability to defeat any adversary. Russia is a wreck. Japan has minuscule international influence compared to its economic strength.
China is a rising power, but it remains a military pygmy.
Even western Europe, an international aggregation whose population and economy exceed those of the United States, has only 10 to 15 percent of America's combat capability. Still, all is not well. Not that U.S. officials have noticed. No matter what they do, they act as if they are implementing justice and truth, if not the American Way. Alas, many people on the receiving end of U.S. policy have a different perception.
