What we learn from history, is that we don’t learn from history.
I used to take that as a cynical motto, in that we really should try harder to learn from history. It’s really the other way around, we need to accept the limits of what we learn from history and not always trying to ‘fight the last war’.
The military hubris of 1914 gave rise to the shameful anti-war appeasement of the 1930s, which led the way to the militarism in Vietnam and Korea, then the non engagement in the Balkans and Rwanda, to the Iraq war, to who knows what justified humanitarian military action we will hesitate in carrying out because of the Iraq mistakes.
We learn from history, that the hindsight from the last crises shouldn’t write the play-book for the next one.
