as long as resources and space is finite and there's plenty of guns and bullets to spare. we'll never learn anything no matter how many times we rebuild. if and when a nuclear war occurs and people survive. it'll just be another decade or so of smaller wars, fallout from nukes, crimes elevating, hunger, poverty, etc etc
I think what the world needs is another hilter. another "great evil" that will force countries to a common cause. Time will tell who rise up to fill that role.
