How does The Post-American World relate to globalization, the United States, and the growth of other nations?

America has been the sole superpower in the post-Cold War era- and as technology and industrial crowd-sourcing have proliferated the necessity and utility of America as a watch dog has been called into suspicion as cultural walls have fallen. Globalization is the relatedness and community between countries that has been established or been amalgamated after the hegemony of America fell. Globalization is the post-modern global state where industry and communication are paramount to progress and individuals thrive through personal empowerment.

The Post-American World relates to globalization, the United States, and the growth of other nations, as it charts the advent of globalization in the post-Soviet era, which ushered in an era of increased global trade, relative stability, American hegemony, and the development of stronger nations relative to the United States.
Following the Cold War and the breakup of the Soviet Union, the United States became the dominant global power and enjoyed social, cultural, political, and economic hegemony. Globalization and the increased diplomacy in a post–Cold-War world led to a period of relative stability and expansion for many developing nations, offering an opportunity to strengthen economies and increase economic as well as global power, China being a prime example.
While America will still continue to be a dominant power globally, its power relative to other nations is diminished, as major international players such as China, India, Dubai, and others continue to modernize and experience great economic growth and stimulation. Because of this period of sustained prosperity, there has been a sort of "leveling of the playing field" globally.
