Yes, that’s my point. Credibility-building worked, and so did brutal repression. This leads me to think that there was some underlying cultural factor present in post-WWII Germany that made it governable by occupiers, by whatever means. The presence of radical Islamist movements appears to correspond to the absence of such a factor. (Sufficiently brutal repression might still work, the way it did for Putin in Chechnya, but it’s not an option for Israel.)
