Some leading party officials disagreed with Goebbels' actions, fearing the diplomatic crisis it would provoke. Heinrich Himmler wrote, "I suppose that it is Goebbels's megalomania...and stupidity which are responsible for starting this operation now, in a particularly difficult diplomatic situation."  The Israeli historian Saul Friedländer believes that Goebbels had personal reasons for wanting to bring about Kristallnacht . Goebbels had recently suffered humiliation for the ineffectiveness of his propaganda campaign during the Sudeten crisis , and was in some disgrace over an affair with a Czech actress, Lída Baarová . Goebbels needed a chance to improve his standing in the eyes of Hitler. At 01:20 am on 10 November 1938, Reinhard Heydrich sent an urgent secret telegram to the Sicherheitspolizei (Security Police; SiPo) and the Sturmabteilung (SA), containing instructions regarding the riots. This included guidelines for the protection of foreigners and non-Jewish businesses and property. Police were instructed not to interfere with the riots unless the guidelines were violated. Police were also instructed to seize Jewish archives from synagogues and community offices, and to arrest and detain "healthy male Jews, who are not too old", for eventual transfer to (labor) concentration camps .
