[Mad Max] What do you think happens to the Citadel and it's surrounding cities after the events of Fury Road?
gpt
Bullet Farm and Gas Town lack the means to assault the Citadel and both are missing leadership and the majority of their war parties, not to mention they're no longer getting food and water from the Citadel.


The Citadel's garage meanwhile is still loaded with vehicles and the Warpups would be loyal to Furiosa. The water, food, and safety would protect them until they could get to the point to where they could send war-parties to defeat the starved and dehydrated remnants of Bullet Farm and Gas Town. 

At which point they are probably maintained by the wretched people who surrounded the Citadel during the events of the Movie and you have a secured area in the Australian Wasteland where food, water, gas, and bullets are in supply and lead by someone benevolent but strong.
