German tourist industry up after 15 Jew-free years < /satirical and cynical parallelism>.
I very much doubt that Western and Asian tourists care at all about the Hutu-Tutsi feud, or can even tell you the history of the tribes.
One big difference. The Germans went along with the Nazis. Their genocide was stopped by outside conquest. The genocide in Rwanda was stopped by the Rwandan victims themselves. The Tutsi rebel army aided by the Hutu moderates did the job.
