Governments and corporations experience inner alignment failures all the time, but because of convergent instrumental goals, they are rarely catastrophic. For example, Russia underwent a revolution and a civil war on the inside, followed by purges and coups etc., but from the perspective of other nations, it was more or less still the same sort of thing: A nation, trying to expand its international influence, resist incursions, and conquer more territory. Even its alliances were based as much on expediency as on shared ideology.

Perhaps something similar happens with humans.
