Predictive programming? Ugh.
I'm really running wild with my thoughts right now, but lets say they start World War 3, things get really nasty. Then when the dust settles they have the perfect excuse "enough is enough" and bring in the one world totalitarian government. I think they would still have at least one opposing country to keep people afraid kind of like in the book 1984, so the world gets split up between 2 or 3 powers that are mirrors of each other while being showed to the people as being drastically different. I think they already have enough of the major powers (China, Russia, Europe, Israel - everyone with nukes) in bed so that they would all play the role.
Maybe it's not on the horizon yet but it seems like a consolidation like that is inevitable.
