"The Spectre isn't some crackpot that runs around killing people and not caring if it destabilizes countries."

Kon knew who the Punisher was. He'd messed up Mexico but good by killing a lot of the cartel leaders and some corrupt government officials without thought for the consequences, and Luthor already seemed to have plans to take advantage of that back home.

"He's sort of like...a natural force of nature in our world. A scary one, but something that's always been there. And if we deliver these people to the police, half of 'em are probably going to wind up getting the death penalty anyway."

Kon slumped back in his chair.

"But like I said, nuclear option. Last ditch. Nightwing's right that we need to try to find some way of depowering him first. And we do have something for that."

Kon reached into one of the little pouches at his belt and pulled out a little lead box about the size of a jewelry box, and placed it in the middle of the table, leaning back and crossing his arms.

"Is that -?" Batman started to ask.

"Yeah, it is. One of Kuk's people gave it to someone that ambushed us on another mission like this to another world. Don't open that when I'm around unless you want to get puked on." Kon shrugged. "Kryptonite doesn't hurt a Kryptonian unless it's from the same universe so it won't work as is, but that's all the more reason that it might be useful. Messing with it to see if it can be worked into something that takes his powers away permanently won't waste anything since it's already useless right now. The worst that can happen is it stays useless. There's a bunch of different types of kryptonite and it has all different effects. Maybe that can be used to make a type of it that gets rid of his powers permanently."
