I'm using "criminals" as a short-hand for "the worst of the worst in terms of rights-violating countries and dictatorial regimes" which is what you initially said.

If there is no such thing as international law, then what "rights" are these countries violating?

> When you have multiple nations that operate independently, each with their own laws and rules, all you can do is get them to agree to certain things, as long as they have some basis upon which to enter into an agreement.

It sounds like you do think all countries should be 'invited to the table' unless they fail to meet a standard which you yourself don't think exists. Confusing.
