Anti-Batman counter-measures
What if, following the "Tower of Babel" fiasco the JLA decided they couldn't trust Batman. After all he's one of the richest men on Earth, is a brilliant strategist, engineer, fighter etc. What if one day he decided to make himself king of the world?
What counter-measures could they (or anyone else for that matter) devise to defeat Batman should he turn rogue?
NOTE: No "Superman throws him into the sun" or anything. Serious answers only.
