Are We Going The Way Of The Roman Republic?

Since reading this fascinating book, I haven't 
been able to shake the feeling that we may be
facing the same demise as that of this once
powerful empire.

I'm not an expert on the history of the Roman empire or on the story of our own, but I do find some striking parallels between the two world powers. 

For example, what is now the United States was also first governed by a monarchy, then as a republic, and then...

Here's the fascinating Roman story:

The Roman Kingdom was  founded in 753 BC and was successful in establishing colonies well beyond its borders. Kings continued to rule the new nation until the monarchy was overthrown in 509 BC. The resulting  Roman Republic was ruled by officials elected by a legislative assembly.

Julius Caesar, one of the more powerful of these elected rulers, was elevated by the Roman Senate to the status of a god after his assassination in 44 BC. His son Octavian proclaimed himself "the son of a god" and was named "Augustus" (majestic) and "Princeps" (first) by the Senate. He was later honored with the title "Pater Patriae" (father of the country).   

Octavian, now known as Caesar Augustus, was emperor at the time of Jesus's birth, and was revered as one of a pantheon of Roman deities. He became known as the first emperor of the expanding Roman empire, effectively ending the republic that had existed for centuries. The Roman Senate wasn't abolished, but became a rubber stamp for his policies. 

Many of the emperors that followed, notably rulers like Caligula, Claudius, Nero and Domitian, had elaborate temples erected for the veneration of the empire, and subjects were to offer token sacrifices as signs of their pledge of allegiance to the emperor ("Caesar is Lord"). Domitian, the virtual dictator in power when the New Testament book of Revelation was written, declared himself "Dominus et Deus" (Lord and god) and persecuted Jews and Christians who refused to comply with his orders. Christians, of course had their own alternative confession, "Jesus is Lord," and opposed any such pledge.

The gradual decline and ultimate fall of the empire occurred over centuries of time. After a thousand-year history, Rome, like every other world empire, eventually came to an end. 

Here is a helpful analysis in a Wikipedia article:

The fall of the Western Roman Empire, also called the fall of the Roman Empire or the fall of Rome, was the loss of central political control in the Western Roman Empire, a process in which the Empire failed to enforce its rule, and its vast territory was divided among several successor polities. The Roman Empire lost the strengths that had allowed it to exercise effective control over its Western provinces; modern historians posit factors including the effectiveness and numbers of the army, the health and numbers of the Roman population, the strength of the economy, the competence of the emperors, the internal struggles for power, the religious changes of the period, and the efficiency of the civil administration. Increasing pressure from invading peoples outside Roman culture also contributed greatly to the collapse. Climatic changes and both endemic and epidemic diseases drove many of these immediate factors. The reasons for the collapse are major subjects of the historiography of the ancient world and they inform much modern discourse on state failure.

History may not repeat itself, but there are often significant parallels we can take lessons from, the first being that no world empire lasts forever.
