Abstract
As Julia Gronnevet said, "comparing the United States to the Roman Empire is a popular pastime" . For instance, in his book entitled Are we Rome?: the Fall of an Empire and the Fate of America (2007), Cullen Murphy established some parallels between these two political entities both perceived, in their days, as the leading world economic power and the principle military power. He wrote that "Americans have been casting eyes back to ancient Rome since before the Revolution" . In effect, like Rome, the United States of America are a vast multicultural state burdened with an expansive and overstretched military which dominate the world with a messianic sense of global mission. Moreover, many historians emphasized the complex relationship between Rome and religion. First of all, the prosperity of this empire was based on the pax deorum. At the time of the foundation of this city by Romulus, gods gave their agreement to the first king of Rome showing that they were in favor of this new human power and that they would provide this people with an indestructible support. Therefore, each event unfavorable to Rome was perceived as resulting from an offense to the gods which should be repaired.
