« I wish it were really possible to make our people at home understand how definitely this martial spirit is being developed in Germany. If this government remains in power for another year, and it carries on in the measure in this direction, it will go far toward making Germany a danger to world peace for years to come. With few exceptions, the men who are running the government are of a mentality that you and I cannot understand. Some of them are psychopathic cases and would ordinarily be receiving treatment somewhere. ». Lettre du 26 juin 1933 au sous-secrétaire d'État William Phillips visible sur http://www.fleetwoodpa.org/messersmith_george/phillips_letter_june_1933.htm.
