Re: DC's New 52: Reviews and Discussion (Spoilers welcolme and likely)
...as opposed to the idea that Batman both likes and hates the current JLI? He didn't seem to be joking about hating some version of the JLI in Justice League 7, and he clearly wants the JLI to succeed in the JLI comics.
I suppose another other option, though, is that Batman sees the only way for the JLI to succeed is for the group to be separate from the UN. In other words, he's lying to Trevor in Justice League 7 in order to get the UN to remove funding.
I think the most reasonable option: poor communication between writers. And bad bad editing.
Batman does not eat nachos.
