Meanwhile, the irritation between France and Germany had increased to the point where open rupture was feared. For years Germany had been waiting for a propitious moment to swoop down on France and overwhelm her. The French intrigues in Morocco, which were leading visibly to a French Protectorate over that country, aroused German resentment, for the Germans coveted Morocco themselves. The Kaiser went so far as to invite Roosevelt to interfere with him in Morocco, but this, the President replied, was impossible. Probably he was not unwilling to have the German Emperor understand that, while the United States would interfere with all their might to prevent a foreign attack on the Monroe Doctrine, they meant to keep their hands off in European quarrels. That he also had a clear idea of William II's temperament appears from the following opinion which I find in a private letter of his at this time: "The Kaiser had weekly pipe dreams." The situation grew very angry, and von Billow, the German Chancellor, did not hide his purpose of upholding the German pretensions, even at the cost of war. President Roosevelt then wrote--privately--to the Kaiser impressing it upon him that for Germany to make war on France would be a crime against civilization, and he suggested that a Conference of Powers be held to discuss the Moroccan difficulty, and to agree upon terms for a peaceful adjustment. The Kaiser finally accepted Roosevelt's advice, and after a long debate over the preliminaries, the Conference was held at Algeciras, Spain. That Roosevelt understood, or even suspected, the great German conspiracy which the Kaiser's hire lings were weaving over the United States is wholly improbable. Had he known of any plot he would have been the first to hunt it down and crush it. He knew in general of the extravagant vaporings of the Pan-Germans; but, like most of us, he supposed that there was still enough sanity, not to say common sense, left in Germany to laugh such follies away. Through his intimate friend, Spring-Rice, subsequently the British Ambassador, he had early and sound information of the conditions of Germany. He watched with curiosity the abnormal expansion of the German Fleet. All these things simply confirmed his belief that the United States must attend seriously to the business of making military and naval preparations.
