The collapse of the United States as the global hegemon constitutes a “systemic revolution” that will transform both the U.S. and the rest of the globe. Such a revolution is different from “normal” political revolutions, which entail an overthrow of the government. A systemic revolution ushers in even broader and more enduring changes in economy, society and culture, and it also transcends national boundaries, affecting other countries and the global system itself. It is a global paradigm shift, and we are right smack in the middle of it.
