Kristallnacht, known as “the night of broken glass” occured 80 years ago throughout Germany and Austria.

Rob Rogers, a former editorial cartoonist for the Pittsburgh Post-Gazette, dubbed Saturday's attack the "Day of Broken Glass."

Himmler and his Nazi thugs had another reason to find and kill von Mises. It was 1938 and he and other enemies of Hitler's state--Jews, like von Mises as well as anti-socialists reformers--held private wealth the Nazi war machine desperately needed to keep running.

Given this unambiguous show of support for charters, how could our governors have the chutzpah to swear an oath to protect public schools, as this would pose a crisis of conscience, not to speak of a conflict of interest akin to setting a fox to guarding a hen house?

Trump does not seem to understand the dangers in the kind of rhetoric that he is using. While we may be a long way away from Kristallnacht, it is worthwhile to point out the signposts on Germany's path to that fateful night. Trump has taken the first tiny dangerous steps towards unleashing forces that could trigger large-scale violence against the Muslim community.
