Commodore
A sequel would be easy. They didn't win the war at the end of ID4, only a battle. All they did was take out the mothership and support vehicles through a network exploit that would only temporarily took out their shields.
Now they have to face the survivors who are no longer vulnerable to that exploit. The war was just beginning and now they have some racist and pissed off aliens to deal with.
