From what Jackson Diehl has written, it appears that the new lessons of history are:
- Unless the current event is exactly like the historical event, there's nothing to be learned from history.
- If somebody has drawn a historic analogy that proves flawed, it conclusively proves that any comparison of the current event to the history event is flawed.
- If somebody claims that a particular lesson is to be learned from a specific historic event, and you disagree, you can reject the idea that anything can be learned from the historic event.
- Absent a perfect analogy, anybody who analogizes a current event to a historic event is being unhelpful.
