Im not a liberal either but im going to answer your dumb ass question, with a statement instead of a list.

By the geneva convention no WMD's are suppossed to be produced. This was put in place to specifically control their production and use.(thats a good thing)

So.... by his agreement countries that dont already have them are subject to invasion for accuiring them.

SO... the subject sort of dies off after you say that.

There is no criteria, there never will be a criteria, because the UN and US wont allow it. It would be a total waste of time to write a list of would be criteria to a dead subject.

anmd not to mention I was never a part of this conversation.... I am the one who never read Orwell.
