[Black Adam] Why doesn't Superman or Justice Society save Khandaq before Black Adam awakens?
gpt
Because to the rest of the world, Intergang was the legitimate authority of Khandaq. You know how people say history is written by the victors? Well, Intergang was winning, by a lot. They have the Eternium to fight off outsiders, and the money to bribe the ones they can't fight. The JSA doesn't maintain their legitimacy by overthrowing governments, and Superman isn't in the business of deposing anyone. 

They might have gotten involved if someone had explained to them what was going on; but the situation clearly wasn't high on Amanda Waller's priority list until Black Adam starting throwing tanks and helicopters around.
