Good stuff, and I'll add my two cents. Christopher we need you on point to help usher in the Christ.

Pros:
1) Fulfills prophecy -- not so much a pro as a critical key point since Elite has so much invested in this.
2) Make it big enough to kill 2 hundred million, and people will realize how destructive war can be and wonder what is it good for (absolutely nuthin, uh-huh!)
3) Make it about religion, i.e. Christian society vs. Muslim society, and it will force people to either go all in for their respective religion or decide that organized religion needs to be done away with, thus laying the ground work for the NWO. I'm betting on the majority being with the latter, especially with the "religion" of modern science there to answer life questions.
4) Massive war = massive spending = massive borrowing = devaluation of the currency = laying the groundwork for a new world currency. Hello, Book of Revelation.

Cons:
1) WWIII won't do much to break down modern society's dependency on technology. If anything, it will promote it. Now a complete breakdown of modern technology, via the worldwide shorting of all electrical circuits for five months -- that will force humanity to stop and re-evaluate what is really important in life. WWIII runs the risk of being just another massive headline generator.
2)If not enough casualties, then it won't be anything more than just another war and just another reason to vote for a different kind of President, revitalization of the hippie movement, etc.
3) Holy sh!t, did I just become a supporter of the Globalist Elite? Hey Christopher, I guess all that programming has worked, eh?
