But is it not possible for societies to change, even if it takes a generation or two for the changes to take hold?
I see your point that no nation, or group of nations, currently have the willpower to invest the troops and aid workers, and funds that are needed to really make an impact . . . but that doesn't mean that it's not possible . . . unlikely, granted . . . but possible.
If no society ever changes . . . then as a species we are doomed to create our own demises.
Reminds me
of a book that has been critically acclaimed.
