Not quite sure which incident you’re talking about but Batman’s saved Gotham and the world more than a few times. He mortally wounded Darkseid in the Final Crisis event, stopped a worldwide Joker plague in Endgame (and Gotham city from a similar fate in the 1989 movie) and so on. As a member of the Justice League, I imagine he’s saved the universe a good few times too.
He didn’t defuse it, he just shielded himself under some heavy iron pipes when it went off.

Sorry, it was behind the pipes, not under them.
