The 9/11 attack was a turning point in the American society, but also in the Muslim world. Because of this attack, global offensive started against the Muslim extremists, and also a big anti Muslim sentiment has developed among the people in the United States, mainly of fear and disgust from the 9/11 attack, as well as other attacks performed by suicide bombers. Because of this, in the United States, a Muslim person is seen with skepticism and as not trustworthy, and it also contributed to the segregation of the Muslims, as well as people keeping away from them.
For a start, the surveillance in airports throughout the world has been modified ( full body scans, long lines, no liquids allowed, etc). Society became aware of terrorism and deportation since 9/11 was massive. Before that date, society has never heard of Al Qaeda, Bin Laden, Taliban movements and terrorist groups.
The fall of Ancient Rome started from about AD 190. The Roman Empire was attacked by tribes such as the Goths and the Vandals. Civil wars in parts of the empire further weakened the rule of Rome and respect for Roman law dwindled as a result.
