Steven Den Beste has a nice description of Japan’s martial history and how it was necessary to end it and entirely restructure their culture in order to get a lasting peace with them.
The point, of course, is that we will almost certainly have to do the same thing with Islam, at least Wahabi Islam, to end the current war. It’s a long read, but a good one. As Steven says, our very existence is not just a threat to them–it’s blasphemy.
