TIL that on hearing about Kristallnacht, Kaiser Willhelm II said from his exile "For the first time, I am ashamed to be a German".

This may not be true. From the German Wikipedia article (translation by Google):

However, he did not publicly criticise the anti-Semitic acts of violence. Foreign newspapers reported that Wilhelm had declared that he was "ashamed to be a German for the first time in his life". The historian Stephan Malinowski describes the interview in which this statement is said to have been made as a fake and refers to several denials by the ex-emperor.
