That's a good question… 

Maybe for Rico charges purposes? Organized crime? 

What enforcement agency would be more appropriate here? ATF?

Wouldn't it be cia (since it's international crime syndicate) and the MI6 since it sounds like we're dealing with Spectre?

gotta watch out for that yakusa and their uranium enriching ways

well i don’t think CIA does actual law enforcement, they can’t charge people with crimes pretty sure — but i can imagine they’d be involved in the uncovering of the criminal conspiracy in first place maybe
