I think the logic runs this way:

Scientists agree resources are running out, which means shortages. Shortages imply conflict or accommodation. Since it's obvious from the various resource treaties that "them as has" ain't gonna share any significant amount with "them that ain't" then the next (unthinkable) step is conflict. Now we're talking about (unthinkable) mass war, for which Europe isn't really ready, mentally or physically, and the USA is.

So we will hear much wishful whining about "why can't we all get along" to which the (unthinkable) answer is: It's who we are, and no one is willing to think about changing the genome, or the culture, so war it is.

There, I fixed that for you.
