Well, when Rome fell in 476 AD it was due to many things but some historians believe christianity played a huge role in the decline of the Empire. Same with today, lots of radical islamic fighters are now planning huge terrorist attacks in the west and it seems like the west is on a collision course... When I said there was many reasons why the Empire fell, I meant that... The Empire fell due to lack of communication between it's provinces and political destress from the senate that caused plenty of civil wars. Eventually Rome had no more military power and the barbarians took over, very different on the decline of Europe and America. I believe the west is declining do to religion attacks and Capitalism Ideology, since huge corporations are independent it will eventually hurt the economy and since the government can't control these private companies, it can be a huge national security risk letting all these billion dollar companies rule the west...
