[ATLA] So can anyone explain King Bumi's strategy to me?

He decided to do nothing despite having a natural fortress as a city, allowed himself to be imprisoned for months while the fire nation enslaves his people and free up forces to conquer other areas, then only fought back on an eclipse where the fire benders lost their powers, despite nobody knowing that was a thing, destroying a lot of his own city to chase them out, and with the fire nation having a lot of free soldiers after taking down Ba Sing Se without a fight and thus can easily attack again and promptly abandons the city to go to the white lotus.

An active resistance would have resulted in more Omashuan subjects being killed by the Fire Nation-- both in battle and in retaliation-- than waiting a few months for a vulnerability to present itself did. He was powerful enough to single-handedly beat back the entire occupying army, but only if he had some kind of advantage. Once they're kicked out the city will be able to withstand a siege. But for that to work he needed to be kept as a hostage rather than executed as the leader of an opposing army.
