While common and almost predictable, there is no denying that surviving Western Empire is a favorite topic of this site. There have been many timelines. However some of the timelines are very ASB or have everything go right despite the odds.
So my question is: realistically, what are the provinces that the last bit of the empire could be pushed to that, given the circumstances, that a truly Roman authority return to the west and why?
Note: if this not clear, I'll try to explain it further.
