Gerard was furious.
"Go tell Zimmermann," he said, "for God's sake to leave America alone. If he keeps this up he'll drag us into the war. The United States won't stand this sort of thing indefinitely."
That evening I went back to the Foreign Office and saw Zimmermann for a few minutes. I asked him why it was that Germany, which was at peace with the United States, was doing everything within her power to make war.
"Why, Germany is not doing anything to make you go to war," he replied. "Your President seems to want war. Germany is not responsible for what the German-Americans are doing. They are your citizens, not ours. Germany must not be held responsible for what those people do."
Had it not been for the fact that the American Government was fully advised about Zimmermann's intrigues in the United States this remark might be accepted on its face. The United States knew that Germany was having direct negotiations with German-Americans in the United States. Men came to Germany with letters of introduction from leading German-Americans here, with the expressed purpose of trying to get Germany to stop its propaganda here. What they did do was to assure Germany that the German-Americans would never permit the United States to be drawn into the war. Because of their high recommendations from Germans here some of them had audiences with the Kaiser.
Germany had been supporting financially some Americans, as the State Department has proof of checks which have been given to American citizens for propaganda and spy work.
I know personally of one instance where General Director Heinicken, of the North German-Lloyd, gave an American in Berlin $1,000 for his reports on American conditions. The name cannot be mentioned because there are no records to prove the transaction, although the man receiving this money came to me and asked me to transmit $250 to his mother through the United Press office. I refused.
When Zimmermann began to realise that Germany's threatening propaganda in the United States and Germany's plots against American property were not succeeding in frightening the United States away from war, he began to look forward to the event of war. He saw, as most Germans did, that it would be a long time before the United States could get forces to Europe in a sufficient number to have a decisive effect upon the war. He began to plan with the General Staff and the Navy to league Mexico against America for two purposes. One, Germany figured that a war with Mexico would keep the United States army and navy busy over here. Further, Zimmermann often said to callers that if the United States went to war with Mexico it would not be possible for American factories to send so much ammunition and so many supplies to the Allies.
German eyes turned to Mexico. As soon as President Wilson recognised Carranza as President, Germany followed with a formal recognition. Zubaran Capmany, who had been Mexican representative in Washington, was sent to Berlin as Carranza's Minister. Immediately upon his arrival Zimmermann began negotiations with him. Reports of the negotiations were sent to Washington. The State Department was warned that unless the United States solved the "Mexican problem" immediately Germany would prepare to attack us through Mexico. German reservists were tipped off to be ready to go to Mexico upon a moment's notice. Count von Bernstorff and the German Consuls in the United States were instructed, and Bernstorff, who was acting as the general director of German interests in North and South America, was told to inform the German officials in the Latin-American countries. At the same time German financial interests began to purchase banks, farms and mines in Mexico.
