As a professor of political science once told our class... "How do you solve long-running civil war?" "Murder all the grandmothers." His point being that they were (a) the only ones who survived into old age (everyone else getting murdered) & (b) were thereby the ones educating a new generation in the hatreds of the old.

Which is order-of-"the time it takes for mindsets to change (usually via death) or new generations to rise into power (~40 years)". I'd never really thought about it that way before.
