On that note, Ul'dah's greatest weakness isn't its divided government.
It's the fact that the closest source of fresh water (the river) is outside the city walls and does not at any point run through the city itself. The Jewel of the Desert is, ironically, the most vulnerable to siege. That said, with as large a standing military force as the Flames are supposed to be, I don't know how either of the other two Eorzean city-states would manage that.
The Empire probably could, if they devoted enough manpower to the task.
...neither Limsa nor Gridania has this sort of strategic liability.
