US. Vs. Rome
The United States and Rome are similar in many ways. In both governments politics are seen as a road to wealth. Also we both fight continuous wars. Lastly in both the middle class is collapsing. I think the United States could fall like Rome because we sometimes have bad leaders. Also we don't seem to try to find a peaceful way to end wars and the wars keep going on.
Why the western roman empire fell.
The western Roman empire fell for many different reasons. One reason was invasions by barbarian tribes. Invasions by barbarians caused the western Roman empire to fall because Rome was sacked twice then a barbarian named Odoacer lead a revolt that over through the last western Roman emperor. A second reason is the rise of the Eastern Roman empire. With the Eastern Roman empire rising caused the western empire to fall because both sides often squabbled over resources and the military and the eastern empire was fortified while the western empire was left vulnerable. A third reason is overexpansion and military overspending. Overexpansion and military overspending caused the western empire to fall because there wasn't a fast enough way for the empire to communicate with other parts and the military was stretched very thin to go over the empire. A fourth reason is government corruption and political instability. Government corruption and political instability caused the western empire to fall because civil war was making chaos and the role of emperor basically a death sentence and was even auctioned off, not even the senate could control the people.
The Eastern Roman empire or the Byzantine empire did not fall until 1453 AD.
