All too likely, I'm afraid.

Hugh - I'll join those disagreeing with you. Cultural disputes arise out of ignorance (prejudice, after all, is almost entirely a subset of ignorance). Deprive peoples & societies of water & energy and, in context of the modern world at least, you automatically force them into poverty.

Solving water & energy poverty may not cure all the worlds ills. Betcha it will make a huge, huge difference, though, & one that becomes more & more effective as time goes on.

Not in my lifetime, though (& I've probably got 60 years yet for "Natural Causes" to kick in)... :(
