a war would likely involve nukes.

Please brother, don't make me imagine a world war with nukes. The whole world is going to collapse, It would take us atleast three century back and it would be the darkest chapter ever.

I think there are some really smart people in the world. We can use them to create beautiful discoveries. Seriously, it sends me shivers thinking of a world war, but it may happen, and I have no control over it. I have to just watch the world wither away.
