I cannot quickly find reference to other material, I have seen on TEDX, but I am sure you will find interesting stuff if you look around. Also, Coursera is coming up with an interesting course:

Coming back to my assessment: I feel much better, when I know Germans are governed by a liberal and democratic government, simply because they have evolved since the Bismarck era, into an extremely cohesive society, where obedience seems to be one of major virtues. This has been reinforced by totalitarian rule under Hitler, and in the East Germany, further perfected under the watchful eye of the Stasi. In such a society, it appears to be more difficult to break out on grounds of moral dissent. In my opinion, this has helped to perpetrate genocide during the WWII and created one of the most inhuman systems under Honecker.
Certainly, many more countries have acts of genocide on their conscience - the last massive one is devolving in front of our eyes in Syria, and probably Stalin's Russia trumped them all.
To get back to the ad: it is simply disrespectful and distasteful. Leica can pride itself for lots of things, but in my opinion should not associate it's name with imagery of war.
I am sure, they did not anticipate how their cameras were going to be deployed by Hitler's army during WWII, but I have seen enough of Leica photographs from that period to feel sick in the stomach when I think of it.
