didn't so much destroy it as remade it.  constantine moved the capitol to new constantinople before rome fell.  long before. so now rome is not the capitol.  and rome had fallen to debauchery and let themselves get sacked. fortunately the capitol was not rome.  it was new constantinople.  the seat of the holy roman empire until around 1850 or so?  and so the roman empire did not fall just rome. and christianity made one of the greatest empires on earth.  out of the skeleton of rome.  meanwhile jews like you never did shit except fuck up things that were too good for you.
