Robin Williams plan would not work, I don't think world peace is going to become a reality any time soon. In fact, the opposite might be happening, look at the increasingly multipolar and competitive world that exists today, dwindling natural resources, etc.

I wonder if Robin Williams was making a joke, if so, its not funny. He makes a lot of foolish assumptions. USA is the cause of all the war in the world??? I think there are about 35 armed conflicts around the world that do not even involve the US directly or indirectly.
